Setup Event Nights

Event Nights

For worlds that should feel calm most of the time, with a big, announced zombie night every few days. Days have no custom waves, ordinary nights only bring a few stragglers, and every 3rd night is a guaranteed horde. Random blood moons hit just as hard.

Read Before You Start if this is your first guide.

Commands

Run these in order:

/za preset standard
/za spawn daytime off
/za spawn chance 0.05
/za events interval 3
/za events chance 1
/za events multiplier 10
/za bloodmoon multiplier 10
/za spawn nightmax 40

• spawn daytime off removes custom waves in daylight.
• spawn chance 0.05 makes ordinary nights quiet.
• Hordes and blood moons multiply the normal chance, so with a low base chance they need a high multiplier: 10 turns the quiet 7.5% night chance into 75% every second.
• spawn nightmax 40 is the ceiling for every night, events included.

Config File

Edit with the server stopped:

# [dayspawning]
enableDaytimeSpawning = false
daySpawnChance = 0.05
# [nightspawning]
maxNightZombiesPerPlayer = 40
# [horde]
hordeIntervalDays = 3
hordeStartChance = 1.0
hordeSpawnMultiplier = 10.0
# [bloodmoon]
bloodMoonSpawnMultiplier = 10.0

These go on top of the Standard values (/za preset standard, or the table on Home).

What To Expect

• Days: no custom waves.
• Ordinary nights: every 6 seconds each player has a 7.5% chance (5% times the 1.5 night boost) of 2 zombies, about one wave every 80 seconds.
• Horde nights: days 3, 6, 9, and so on. A title announces the horde at dusk. Waves are checked every second at 75% with 5 zombies each until 40 zombie-class mobs surround each player, and new ones keep coming as you kill them. It lasts about the whole night (10 minutes).
• Blood moons: 15% of nights, any night. Same 75% every second, with 4 zombies per wave. A blood moon on a horde night reaches 100%.
• Difficulty: scaling still runs from day 3 to day 50, so horde nights get harder.

Tuning

To make it...	Run
Even quieter between events	/za spawn chance 0.02 and /za events multiplier 20 (one wave every 200 seconds or so, 60% per second during hordes)
Event nights less intense	/za events multiplier 5 and /za bloodmoon multiplier 5
Bigger event crowds	/za spawn nightmax 80
Bigger blood moon crowds only	/za spawn bloodmoonmax 100
Larger event waves	/za events amount 8 and /za bloodmoon amount 6
Events further apart	/za events interval 7
Only scheduled events, no random blood moons	/za bloodmoon off
No blood moons for the first two weeks	/za bloodmoon startday 14
Zombies burn at dawn after the event	/za burn on
Siege nights where zombies break in	add the commands from Siege and Base Defense
Stronger after each event	/za scaling steps 3 (strength rises the morning after every horde from the second one on, because Standard scaling starts on day 3)

Horde multipliers go up to 20 and blood moon multipliers up to 50. Once the base chance times 1.5 times the multiplier reaches 1.0, every check is already a wave, so higher values change nothing.

Undo

/za preset standard brings back the normal balance, daytime waves, and the normal night cap.
