⚔ GameMod

— Fabric 1.21.x

A full-featured mini-game manager with countdown display, settings GUI, custom spawn radius, and world border control.

Required Dependencies (install alongside this mod)

Commands (requires op level 2)

Game Control

Settings

Settings GUI (ModMenu)

Open the Mods screen in-game → find Game Mod → click the ⚙ button.

Categories:

• Display — boss bar vs action bar toggle
• Spawn Location — X / Y / Z coordinates + scatter radius
• World Border — game size and post-game reset size
• Cooldown — duration in s / m / h format

Settings are saved to config/gamemod.json automatically.

How it Works

/game start flow

1. Checks for an active countdown or game (blocks if already running)
2. If cooldown > 0: counts down, displaying progress on all players' screens
3. At zero (or instantly): teleports all online players to a random position within the spawn radius, sets world border centred on the spawn coordinates, sets everyone to Survival

Random radius teleport

• If radius = 0: all players land on the exact spawn point
• If radius > 0: each player gets a random angle and distance within the radius; Y is found automatically using the terrain heightmap (players always land on solid ground, not in mid-air or underground)

Eliminated players

When a player dies while a game is active they are automatically switched to Spectator mode. /game stop returns all spectators to Survival.
