Your son wants to create a new game mode in Minecraft. It needs to be programmed in Java. Here are some tips from AI: Technical specifications for the development of the Minecraft plugin "King Hunt." * A plugin needs to be developed for Minecraft Java Edition under Paper version 1.21.11. The plugin must work on a regular Paper server, be compatible with Aternos, and consist of a single ready .jar file without the need to install additional plugins. General idea King Hunt is a PvP mode designed for a group of friends (ideally 4 people, preferably supporting up to 8 players). The main goal of the game is to hold the title of King for as long as possible. The player who has spent the most time as King wins, not the one who has killed the most. In summary: a fully ready King Hunt plugin for Paper 1.21.11 is needed, which can be immediately uploaded to the Aternos server and played with friends without installing additional dependencies. The main goal of the mode is to hold the title of King for as long as possible while participating in dynamic PvP battles with a shrinking map and random game events.
