Cooperative End Access

Do you have friends that...

• won't tell you when they're going to beat the Ender Dragon
• can't stop themselves from solo'ing the Ender Dragon
• are named Sung Jinwoo and (scariest of all) are voiced by Kazuya Kinoshita

Then Cooperative End Access is for you!

What is Cooperative End Access?

Cooperative End Access is a Paper plugin for survival multiplayer servers (SMPs) on Minecraft 1.21 to 26.1.2 that ensures that the dragon fight will always be a group activity.

The plugin accomplishes this goal by restricting the number of Eyes of Ender that each player can place in a stronghold Ender Portal structure and requiring all players to be present before the portal can open.

How do I use this plugin?

1. Download the latest version of this plugin for your Minecraft version off Modrinth.
2. Move it to your plugins/ directory.
3. (Re)start the server.

You should ideally add this at the very start of your SMP. This plugin does not currently provides tools to locate or close existing Ender Portals or retroactively track existing Eyes of Ender.

What gameplay changes does this introduce, exactly?

Each player has a limited number of Eyes of Ender (set by max_eyes_per_player) that they can place in a standard 5x5 End Portal structure. Placing a single Eye of Ender in a structure marks that player as a "contributor" to that particular Portal.

Filling all 12 End Portal frames will not immediately open the End Portal like in vanilla. All contributors to a particular End Portal must also be present in the portal room for the portal to open. If a contributor were to leave the portal room, the portal will close.

Players may also remove eyes from a portal frame, but only those that they placed themselves. Removing an eye while a portal is open will close it.

Once the Ender Dragon is defeated for the first time, End Portals will revert to their vanilla functionality.

What should I not expect from this plugin?

On a technical level...

• This plugin does not handle weirdly-shaped End Portal frame structures. It expects you to be playing with a standard End Portal structure (5x5, all frames inward).
• This plugin does not handle existing Eyes of Ender placed in the frames (player-placed before the plugin was added or naturally-spawned ones).
• This plugin does not handle existing, open End Portals. Break them yourself.
• This plugin does not handle having killed the dragon before adding the plugin.
  • If you would like to replicate the functionality of this plugin after killing the dragon, I recommend using this handy little command: find ./plugins -maxdepth 1 -type f -name 'CooperativeEndAccess-*.jar' -delete

On a social level...

• This plugin does not guarantee that your SMPs will survive more than one week.
• This plugin does not guarantee that your friends won't be upset if you suddenly spring this plugin on them without telling them.
• This plugin does not guarantee that opening the End cooperatively will actually be any fun.
• This plugin does not guarantee that your friends won't beat the Ender Dragon without you, but does guarantee, if they do beat the Ender Dragon without you, that'll be together, minus you.

What configuration options do I have?

This plugin offers a lot of user-facing feedback. You can configure mechanics (like eyes required) and effects (like messages and sound effects) in your config.yml. See the sample config.yml here for exact configuration options.
