Arena_lib is a library for Minetest working as a core for any arena minigame you have in mind.
It comes with an arena manager and a signs system. The latter creates a bridge inside your own server between the hub and your actual mod (deathmatch, capture the flag, assault, you name it). In other words, you don't have to do the boring job and you can focus exclusively on your minigame(s) :*

Config

Install it as any other mod
Launch the world at least once with arena_lib enabled and then check worlds/nameofyourworld/arena_lib to customise it
(modders only) Dive into the full documentation to understand how to create minigames

Dependencies

(bundled) ChatCMDBuilder by rubenwardy
signs_lib by Vanessa Dannenberg
(optional) Parties by me: use it to be sure to join the same arena/team with your friends

Add-ons

Hub by me: use it if you're aiming for a full minigame server. It can't be set as an optional dependency, since arena_lib is a hard dependency of Hub in the first place (and MT doesn't like cross dependencies)

Known conflicts

Beds or any other mod overriding the default respawn system
SkinsDB or any other mod applying a 3D model onto the player, if teams_color_overlay is used
Weather or any other mod changing players skybox at runtime (custom celestial vaults will be overridden)

Mods relying on arena_lib

Block League
Murder
Skywars
...and many more! (full list)

Feel free to:

open an issue
submit a merge request. In this case, PLEASE, do follow milestones and my coding guidelines. I won't merge features for milestones that are different from the upcoming one (if it's declared), nor messy code
