Falling Hazard

Optional room hazard. Off by default on new rooms.

• Drop rooms (direction: down): descending particle plane.
• Climb rooms (direction: up): rising flood (particles, water, or lava).

Settings live on each room YAML under falling-hazard (not in config.yml). Configure from the wand hotbar Falling Hazard item (magma cream). Room direction is set in Room Settings (nether star).

Staff how-to

1. Enter wand edit for the room.
2. Set Direction in Room Settings (Down = drop, Up = climb).
3. Right-click Falling Hazard (magma cream). Opens the menu when GUIs are on; toggles when GUIs are off.
4. Enable, set style (climb), start mode / interval / hit modes / particle.
5. Save the room (/sf wand finish). Test a run.

Drop behavior (direction: down)

1. Starts when a floor begins. If start mode is After delay, the delay runs on every floor (not only floor 1).
2. hazard.warning is sent when a delay starts. hazard.started is sent when the plane first activates on floor 1.
3. A short grace period (~2 seconds) lets players settle before damage.
4. A particle plane descends across the current floor’s block bounds.
5. Above, in plane, and below use the modes you set.
6. Pauses while a cleared floor’s countdown runs and during drop/paste.
7. Resumes at the same world Y it paused at (does not snap to the next ceiling).
8. If the plane is far above the current floor, it speeds up to catch up, then returns to normal speed when near that floor’s ceiling.
9. Stops when it reaches the current floor bottom (no lingering damage pool).
10. Paste failures clear the pause so the hazard is not stuck off for the rest of the run.

Climb flood (direction: up)

1. Flood starts in the starter footprint and rises one layer at a time. XZ grows with revealed climb segments.
2. Style: particles (recommended default), water, or lava (real blocks; flow cancelled so they do not cascade through parkour). Lava flood cannot ignite or burn room blocks. Session wipe also snuffs leftover fire in the flood volume.
3. Does not pause between floors. It keeps rising while floors reveal.
4. Soft fail: if the flood surface is more than climb-overhead-fail-blocks above eye height, the player dies (lives apply).
5. Standing inside the flood volume deals contact damage for all styles (particles, water, lava), using hit mode / damage from the menu. Depth uses the flood surface, so air pockets and leftover platforms at that height still hurt. Water/lava still apply vanilla drown/burn on top.
6. Soft escape vs clear: hazard On wins by reaching the top (proximity reveal + mobs on appear). Off is Clear mode with no flood: Stay / Ladder / Stair pack opens a path; for Ladder/Stair the party climbs up, the hole closes, then mobs spawn. See Gameplay Guide.
7. Respawn and late join prefer pads above the flood surface.
8. Flood fluids and any leftover fire are wiped on victory, fail, or session cleanup.

Contact damage uses normal player.damage, so party lives still apply (anti-cheese.lives). Volume ticks about twice per second. Climb weaknesses can multiply rise speed (flood-interval-mult) or contact damage (flood-damage-mult).

Creative and spectator players are ignored. Invulnerable players (including a short post-respawn window) are ignored.

Main menu

Control	Action
Enable	On / off for this room
Style	Particles / Water / Lava (climb flood; drop rooms stay particle-driven)
Start	Floor start or After delay (+ delay seconds)
Fall / Rise interval	Ticks between steps (left −10 · right +10 · shift ±40)

Damage	Amount when a damage mode is active
Particle	Left next · right previous presets. Shift-click to type any Bukkit particle name in chat (clickable suggestions; type cancel to abort)
Color	When the particle supports color (left / right)
Advanced	Density, spread, slice height, size, render interval

Blocks moved each tick interval still come from speed in the room YAML (default 1.0). Drop catch-up multiplies that step when the plane is far above.

Messages

In messages.yml:

Key	When
hazard.warning	Start delay begins
hazard.started	Plane activates (floor 1)
editor.hazard-enabled / editor.hazard-disabled	GUI-off toggle feedback
editor.particle-input-*	Shift-click particle chat flow

Tips

• Instant kill above the plane pairs well with the default lives: 3 pool, or lives: 0 for unlimited retries.
• Lower density and particles-per-point if the plane causes lag.
• Keep floor bounds accurate; the plane covers the pasted schematic’s block box.
• Use a lower fall-interval (faster ticks) for tighter pressure; catch-up handles deep multi-floor gaps automatically.
