I'm kzxm1, a UK-based, mostly paid dev making PvP, SMP and FFA features on Paper 1.21.11. Custom weapons, duel systems, ability Skripts and the odd Discord bot when you need one.
Inventory
A few favourites. Everything here is running, or has run, on a live server.
Custom PvP weapons, each with its own ability. Everything is set up in YAML, so new weapons need no code. Players can use them without op; only the menu and admin commands are locked.
A full SMP system: strength levels you can gain, lose and withdraw, plus a passive and an ultimate for every weapon type. Covers sword, axe, trident, shield, bow and crossbow.
Duel rooms for FFA servers. Players queue with /1v1 and get dropped into their own arena. Every colour and message lives in config.yml, so it fits any server's theme.
Services
Proper compiled plugins for Paper and Spigot, built from scratch or fixed up from what you've already got.
Fast to build and easy for you to tweak later. Great for SMP systems, events and server-specific features.
Smaller bots that hook into your Minecraft server or help run your community.
Ordering
Have a look at how ordering works, then join the Discord and make a ticket. Right now 4/4 slots are free.
