Singleplayer

Simply press the 'Singleplayer' button on the main menu and you can create a regular vanilla minecraft and play it any time.

Importing and Exporting Worlds

The worlds are stored in your browser's local storage, you can export them as EPK files and import them again on all other Eaglercraft sites that also support singleplayer. You can even copy an exported world to an entirely different computer, or send it to a friend, and import it and continue playing with all your progress saved.

LAN Worlds

Eaglercraft fully supports LAN worlds, you can share your world with any player and they can connect directly to it as if you are running a server in your browser.

LAN worlds will work between any two devices connected to the internet, you are not limited to only players connected to your Wi-Fi network

To open your world to LAN, go to the pause menu and click 'Open to LAN'. You can configure the gamemode and cheats and if you would like to hide your LAN world. When you do not hide your LAN world, it will appear on the Multiplayer screen from the main menu to anybody else also on your Wi-Fi network. Set the world hidden if you are at school or something and don't want everyone else in your class to join as well and start griefing.

When you open the world to LAN it will give you a 'join code'. Simply share the code with your friends and they can visit the Multiplayer screen from the main menu and click 'Direct Connect' and enter the code and they will be able to join your world.

Make sure they add the relay server your game opens the LAN world on to their "Network Settings" menu accessable from the Multiplayer screen. You simply must send them the URL indicated in the pause menu once the world is opened and they can use the "Add Relay" option to add the URL to their list.

THIS IS A REQUIRED STEP FOR A PERSON TO JOIN YOUR WORLD, IF THEY DO NOT HAVE THE RELAY YOUR WORLD IS HOSTED ON ADDED TO THEIR "Network Settings" THE GAME WILL BE UNABLE TO LOCATE THE WORLD

Public LAN Relays

Here are some public relay servers you can use:

Creating a LAN Relay

Simply download stable-download/sp-relay.jar and run java -jar sp-relay.jar

Run java -jar sp-relay.jar --debug to view debug info like all the IPs of incoming connections, as it is not shown by default because logging all that info will reduce performance when the relay is being pinged many times a second depending on it's popularity.

Edit the relayConfig.ini file generated on first launch to change the port and configure ratelimiting and such, and relays.txt to change the list of STUN and TURN relays reported to clients connecting to the relay, which are required to correctly establish a P2P LAN world connection in browsers

The origin-whitelist config variable is a semicolon (;) seperated list of domains used to restrict what sites are to be allowed to use your relay. When left blank it allows all sites. Add offline to allow offline download clients to use your relay as well, and null to allow connections that do not specify an Origin: header. Use * as a wildcard, for example: *.deev.is allows all domains ending with "deev.is" to use the relay.

Multiplayer

Multiplayer functions like vanilla Minecraft, allowing you to join normal Minecraft servers like a normal client.

Public clients and servers

There are multiple official clients hosted by lax1dude, here is a small list:

Alternatively, there is a server list[^2] to find servers.

[^2]: Server list is currently being rebuilt, use official client for now

Creating your own server

There are multiple parts to a server, mainly consisting of a regular 1.5.2 Bukkit server, and a modified version of Bungeecord called EaglercraftBungee, which on top of the regular Bungeecord functionality, it translates WebSocket connections to raw TCP connections which Bukkit can understand.

You may also want to set up your own client, allowing you to control default server listings, resource packs, and an overall faster connection due to less load.

If you want to use a domain for your server, a reverse proxy can be set up to enable extra functionality within EaglercraftBungee. NGINX is recommended, and a tutorial is included here. This is optional, and can be skipped by just connecting with the IP.

If replit is acceptable, you can use this to automatically set up everything for a server, otherwise, look below for instructions

Creating a server - Bukkit

  1. Check if Java is installed. You can download it from https://www.java.com/en/download/
  2. Download the stable-download/stable-download.zip file from this repository
  3. Extract the ZIP file you downloaded to a new folder
  4. Open the new folder, go into the java/bukkit_command folder
  5. In Windows, double-click run.bat. It should open a new terminal window
    run.bat
    Some computers may just say 'run' instead of 'run.bat', both are correct
  6. On macOS or Linux, google how to open the terminal and use the cd command to navigate to java/bukkit_command
    Then, in that folder, run chmod +x run_unix.sh and then run ./run_unix.sh. It should start the same server
  7. To add some bukkit plugins, download the plugin's JAR file for CraftBukkit 1.5.2 and place it in java/bukkit_command/plugins (See https://github.com/lax1dude/eaglercraft-plugins/ to download some supported plugins)

Creating a server - EaglercraftBungee

  1. In the same new folder, go into the java/bungee_command folder
  2. In Windows, double-click run.bat. It should open a second terminal window
    Keep both the first and second terminal window you opened, just minimize them, don't close
  3. On macOS or Linux, repeat step 7 in Creating a Server - Bukkit, but navigate to java/bungee_command this time
  4. To add some bungee plugins, download the plugin's JAR file and place it in java/bungee_command/plugins

There are alot more configurations in bungeecord, but this should set you up

Your server is now ready. Visit any client, and go to 'Multiplayer' from the main menu. Select 'Direct Connect', type 127.0.0.1:25565 and press 'Join Server' It should allow you to connect, if not, check the two terminal windows for errors

Creating a client

  1. To install, upload the contents of stable-download/web to a web server.

    • There are multiple ways of setting up a web server. NGINX is a powerful web server, but alternatives like Web Server for Chrome may be easier to set up.
      • A quick crash course on setting up NGINX is provided here, FOLLOW STEPS 1 AND 2 ONLY, then navigate to /var/www/html and upload the contents of stable-download/web there.
    • If you had installed NGINX earlier as a reverse proxy, you can also use it to host the client, follow the steps above ^^^
      • Make sure that the URL to connect to the client and the server are separate, preferably with a path, like https://eaglercraft.example.com/server

  2. The 'web' folder will not work if you open it in your browser locally! If you see 'file:///' in the URL you are doing it wrong. You need to upload the folder to an HTTP or HTTPS server and access it over the internet via http:// or https://. The game will not load otherwise, this is not a bug

  3. To modify the list of default servers, modify the window.eaglercraftOpts variable in index.html.

  4. A full guide on how to configure eaglercraftOpts is coming soon, but it should be fairly intuitive to figure out how to set it up based on what the default values already are when you look in stable-download

  5. To create a link to your site that automatically joins the server, add a ?server= variable to the URL, like (for example): https://g.deev.is/eaglercraft/?server=127.0.0.1:25565 will automatically join ws://127.0.0.1:25565/ as soon as the player finishes setting their username and skin

EaglercraftBungee Configuration

MOTD

Authentication

To enable the /login and /register commands in EaglercraftBungee, you can edit this portion of config.yml

authservice:
  authfile: auths.db
  register_enabled: true
  ip_limit: 0
  join_messages:
  - '&3Welcome to my &aEaglercraftBungee &3server!'
  login_timeout: 30
  enabled: false

Moderation

Miscellaneous

Username Bans

IP Bans

In order for IP Bans to work, a a reverse proxy is required, and forward_ip needs to be configured, otherwise it cannot ban the user's IP

Client Bans

enable_web_origin_blacklist: false
origin_blacklist_block_replit_clients: true
origin_blacklist_block_offline_download: true
origin_blacklist_block_missing_origin_header: true
origin_blacklist_use_simple_whitelist: true

Then, add your domain to origin_blacklist_simple_whitelist like this:

origin_blacklist_simple_whitelist:
- type the name of your client's domain here

Then, unless still you want it as an option for your players, disable the offline download so hackers don't use it to bypass the whitelist, as it is not blocked in whitelist mode by default:

origin_blacklist_block_offline_download: true

Others

ratelimit:
  ip:
    enable: true
    period: 90
    limit: 60
    limit_lockout: 80
    lockout_duration: 1200
    exceptions: []

If you would like to signal the client to disconnect from your bungeecord and reconnect to a different bungeecord, configure an entry in the servers part of config.yml like this:

test:
  redirect: wss://ServerHere/
  restricted: false

In this example, sending a player to the server test, such as when they enter a portal or type /server test, will trigger their client to disconnect from your bungeecord and then automatically reconnect to wss://ServerHere/ as if it was entered via "Direct Connect"

Creating a Reverse Proxy - NGINX

Here is a quick crash course of setting up NGINX on Linux, specifically on Debian distributions.

Here are some google searches for other distributions:

  1. Open up your terminal, and run
    sudo apt update and sudo apt install nginx

  2. Open any web browser, and search for localhost in your search bar. You should see something like this:Welcome to nginx

  3. Navigate to NGINX's configuration with cd /etc/nginx/sites-enabled.

  4. Create a new configuration file with your domain name, for example nano eaglercraft.example.com

  5. Paste in the following code into the file. Replace example.com with your own domain, and app_server_address as the ip:port of your EaglercraftBungee server you want the URL to connect to.

    server {
listen 80;
listen [::]:80;

server_name example.com eaglercraft.example.com;

location / {
    proxy_pass app_server_address;
    include proxy_params;
}
}

  6. Now, restart NGINX with sudo service nginx restart and you should be good to go!

NGINX Configuration

To implement the following configuration, add the lines below the proxy_pass line.

add_header X-Frame-Options "SAMEORIGIN";
add_header Referrer-Policy "strict-origin";
add_header X-XSS-Protection "1; mode=block";
add_header Content-Security-Policy "default-src 'self' 'unsafe-inline'; img-src 'self' 'unsafe-inline' data: blob:; connect-src 'self' ws: wss:; upgrade-insecure-requests";
(not fully tested, excuse the scroll bar)

Plugin Development

To develop a plugin, download stable-download/java/bungee_command/bungee_dist.jar and add it to the Build Path of your Java IDE. Develop the plugin just like a regular BungeeCord plugin, see EaglerMOTD for an example.

Test your plugin by exporting it as a jar and putting it in the '/plugins' directory of EaglercraftBungee and then clicking 'run.bat'

New Events:

Register event handlers using the standard BungeeCord @EventHandler annotation in your Listener class

Compiling

To compile for the web, run the gradle 'teavm' compile target to generate the classes.js file.

The LWJGL runtime is no longer supported it is only included for reference

Creating a resource pack

Contributing

All I really have to say is, tabs not spaces, and format the code to be like the eclipse auto format tool on factory settings, but also run-on lines of code long enough to go off the screen and single line if statements and other format violations in that category are welcome if it helps enhance the contrast between the less important code and the more important code in a file. Don't commit changes to javascript/classes.js or javascript/classes_server.js or javascript/assets.epk or anything in stable-download/. I'll recompile those myself when I merge the pull request.
