Troubleshooting

No Zombies Are Spawning

Check these first:

/zdayspawn status
/zhorde status
/zscaling status

Common causes:

• custom spawning is disabled
• spawn chance is too low
• spawn interval is too high
• nearby zombie cap is already full
• player is in Creative or Spectator
• daylightSpawnStartDay is delaying daytime spawns
• maxBlockLightForSpawning is blocking lit areas
• requireOpenSkyForOverworldSpawns is blocking covered areas
• minimum spawn distance is too large to fit inside the spawn range
• the server is on Peaceful

/zdayspawn status prints a warning when the distance settings are impossible. For example, range 30 supports a maximum horizontal distance of about 42 blocks at the square's corners. A minimum of 43 or more pauses custom spawning.

Quick test settings:

/zdayspawn enabled true
/zdayspawn chance 1.0
/zdayspawn interval 20
/zdayspawn amount 3
/zdayspawn attempts 40
/zdayspawn max 100
/zdayspawn daylightstart 0
/zdayspawn maxlight -1
/zdayspawn sky false
/zdayspawn debug true

After testing, turn debug off:

/zdayspawn debug false

Zombies Only Spawn Near Villages Or Cleared Areas

This usually means the terrain around the player has fewer valid spawn spaces. Snow layers, water, heavy vegetation, roofs, cliffs, and uneven terrain can reduce valid spots.

Try:

/zdayspawn sky false
/zdayspawn attempts 40
/zdayspawn range 40

Torches Do Not Protect Bases

Set:

/zdayspawn maxlight 7

Or in the config:

maxBlockLightForSpawning = 7

If it is -1, block light is ignored.

Zombies Are Too Fast Or Too Strong

Check:

/zscaling status
/zattr status

To temporarily turn off scaling:

/zdayspawn scaling false
/zdayspawn attributes false

Baby Zombies Are Annoying

Disable new baby zombie-class spawns:

/zdayspawn babychance 0.0

Or in the config:

babyZombieChance = 0.0

Players Removed The Mod But Zombies Still Feel Boosted

Those were probably zombies that already existed and had boosted attributes saved into the world.

Best prevention:

/zcleanup uninstall

Run it before removing the jar.

Zombies Are Breaking Player Builds

Block breaking is disabled by default. Check the live state:

/zblockbreak status

Disable it immediately with:

/zblockbreak enabled false

If you want block breaking but need safer rules, use range 1, lower the hardness limit, protect containers, tool-required blocks, and lights, and keep mobGriefing protection enabled.

Server Lag

Use safer values:

/zdayspawn interval 180
/zdayspawn amount 1
/zdayspawn max 30
/zdayspawn attempts 5
/zdayspawn debug false
