v0.1.0-alpha · Paper / Purpur · MC 26.1+

One jump. Everybody jumps.

OneJumpAllJump is a chaotic Paper plugin with a simple premise: a single player jumps, and the entire server is launched with them: random launch power, particles, sounds and titles included. Fully configurable chaos, down to the tenth of a tick.

How the chaos works

Trigger. Check. Launch. Erupt.

Every global jump follows the same chain: documented, predictable chaos.

One player jumps

Any real jump on the server fires Paper's PlayerJumpEvent: that's the whole trigger surface.

The checks decide

Cooldown, trigger odds and the world whitelist/blacklist run first. Fails stay silent.

Everyone launches

All online players are yeeted the same tick, each with an independent power between 0.35 and 1.10.

The server erupts

Particle bursts, synchronized sounds, GLOBAL JUMP titles, villager trails and a chat broadcast.

Tuned by hand

Chaos with an off-ramp

Every dial is in one config.yml Launch power, cooldowns, odds, worlds, particles, sounds, titles and broadcasts. Whitelist your survival world, blacklist the lobby, and reload live with /onejump reload.

• World whitelist / blacklist: chaos only where you want it
• Per-player cooldown + trigger chance for pacing
• Cached config: zero per-jump file reads
