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 or clients that also support singleplayer (including kone client). 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

kone client 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 (even if they're using a different Eaglercraft client).

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:

wss://relay.deev.is/
wss://relay.lax1dude.net/
wss://relay.shhnowisnottheti.me/

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

Alternatively, there is a server list¹ to find servers.

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.

Creating a server - Bukkit

Check if Java is installed. You can download it from https://www.java.com/en/download/
Download the stable-download/stable-download.zip file from this repository
Extract the ZIP file you downloaded to a new folder
Open the new folder, go into the java/bukkit_command folder
In Windows, double-click run.bat. It should open a new terminal window

Some computers may just say 'run' instead of 'run.bat', both are correct
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
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

In the same new folder, go into the java/bungee_command folder
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
On macOS or Linux, repeat step 7 in Creating a Server - Bukkit, but navigate to java/bungee_command this time
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

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
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
To modify the list of default servers, modify the window.eaglercraftOpts variable in index.html.
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
To create a link to your site that automatically joins the server, add a ?server= variable to the URL, like (for example): https://kone-client.ga/?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

To change your server's MOTD and icon, edit the motd1: tag of the listener config in java/bungee_command/config.yml, and replace server-icon.png in the folder where the config file is. Use & to add color/formatting codes. The server list will downscale your icon to 64x64 pixels
You can give your MOTD multiple lines, add a motd2: to define a second line
For an animated MOTD and icon, install EaglerMOTD: https://github.com/lax1dude/eaglercraft-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

authfile Sets the authentication database file, which is compatible with AuthMe
register_enabled Turns register command on and off
ip_limit Sets the max number of registrations per IP, 0 = unlimited
join_messages List of messages to show the player when they join
login_timeout Sets how many seconds players have to log in before they are kicked
enable Turns login commands on and off

Moderation

Miscellaneous

If you use /op on your server, keep in mind that if you "/op LAX1DUDE", a player joining as 'laX1DUDE' or 'LaX1dUdE' or 'lax1dude' will all have /op too. To solve this problem, force all operators to only be able to join with all lowercase ('lax1dude') letters in their usernames by moving 'BitchFilterPlugin.jar" into "java/bukkit_command/plugins" and then register every op username lowercase
To disable voice chat, set voice_enabled: false in the bungeecord config.yml

Username Bans

To ban a username on Eaglercraftbungee, use: eag-ban <username>
You can edit bans.txt in your EaglercraftBungee folder, the server automatically reloads the file when it is saved
To ban users by regular expression, use: eag-ban-regex <regex> with a regular expression to match the username in lowercase

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

To ban an IP on Eaglercraftbungee, use: eag-ban-ip <ip>, or eag-ban-ip <name> to ban the IP of a player automatically
To ban a range of IP addresses, use slash notation to define a subnet. Example: eag-ban-ip 192.168.0.0/8
To ban users by wildcard (*) use: eag-ban-wildcard <text>* or eag-ban-wildcard *<text> or eag-ban-wildcard *<text>*

Client Bans

EaglercraftBungee has a built in domain blacklist that updates automatically, you can disable it by setting this in config.yml:

enable_web_origin_blacklist: false

To block all clients on replit from joining, set this to true in config.yml:

origin_blacklist_block_replit_clients: true

To block all offline-download clients, set this to true in config.yml:

origin_blacklist_block_offline_download: true

To block the debug runtime (or other desktop clients), set this to true in config.yml:

origin_blacklist_block_missing_origin_header: true

To add your own blacklisted domains, create a file called origin_blacklist.txt in your bungeecord directory and put the regular expressions inside, one on each line. There 's also a domain command in the console to view a player's domain, and a block-domain and block-domain-name and unblock-domain command to manage the local origin_blacklist.txt from the bungee console (if you don't know how to edit a file on your own). The list reloads automatically when changes to the file are detected.
To configure bungee to block connections from all clients except your own, set this option:

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

The server has built in DoS protection, reset it via typing 'eag-ratelimit reset' in the bungee console**
Rate limiting is possible, but a reverse proxy is required, and forward_ip needs to be configured to use rate limiting, otherwise it will be disabled by default

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

enable enable rate limiting
period and limit set the number of requests (limit) can be made in (period) number of seconds
limit_lockout and lockout_duration set the number of requests (limit_lockout) that can be made in (period) seconds before the IP is blocked for lockout_duration number of seconds
exceptions a list of IP addresses that should never get rate limited. Local IPs like 127.0.0.1 and 192.168.*.* and such are set as exceptions by default
Redirecting the client to a new WebSocket

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:

Open up your terminal, and run
sudo apt update and sudo apt install nginx
Open any web browser, and search for localhost in your search bar. You should see something like this:
Navigate to NGINX's configuration with cd /etc/nginx/sites-enabled.
Create a new configuration file with your domain name, for example nano eaglercraft.example.com
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;
    }
}

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.

To stop people from using bookmarklets to load a client from a different URL onto your official URL via XXS, add these headers to NGINX:

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)

To use IP bans and rate limiting, add proxy_set_header X-Real-IP $remote_addr to your proxy configuration

Others

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:

net.md_5.bungee.api.event.WebsocketMOTDEvent: Triggered when a client or website requests the MOTD
net.md_5.bungee.api.event.WebsocketQueryEvent: Triggered when a client or website requests a query. This happens when a site opens a text WebSocket to a listener and sends a single string Accept: <query> packet. Can be used to provide additional custom statistics to server list sites supporting integrated WebSocket queries

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

To make a custom resource pack for your site, clone this repository and edit the files in lwjgl-rundir/resources.
When you are done, navigate to epkcompiler/ and double-click run.bat. Wait for the window to say Press any key to continue... and close it. Then, go to ../javascript in the repository and copy javascript/assets.epk to the assets.epk on your website
If you're on mac or linux, navigate to the epkcompiler folder via cd and run chmod +x run_unix.sh and then ./run_unix.sh to do this, then copy the same javascript/assets.epk to the assets.epk on your website

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.
