v1.7.0 — Zomboid SandboxVars world tuning
Project Zomboid's world is now fully tunable from the panel — the follow-up to v1.6.1's server-settings expansion.
Zomboid: SandboxVars world tuning (~70 new settings)
Four new tabs on Zomboid servers expose the game's sandbox surface — the same options as single-player's Custom Sandbox menu:
- Zombies — population preset plus the real dials: speed (sprinters → shamblers), strength, toughness, infection transmission & mortality, cognition, memory, senses, activity hours, and the
ZombieConfigmultipliers (overall/start/peak population, peak day, respawn hours & fraction, group sizes, sound-follow distance). - Loot — all ten rarity categories (food, canned, weapons, firearms, ammo, medical, mechanics, survival gear, literature, other) plus loot-respawn rules.
- Survival — XP multiplier, hunger/thirst rates, nutrition, food rot & fridge effectiveness, farming & foraging abundance, injury severity, bone fractures, multi-hit melee, free trait points, starter kit, corpse cleanup.
- Vehicles — spawn rate, condition, gas amounts & consumption, locked cars, alarms, traffic jams, crash damage, easy-use mode.
- Plus world/time options in the World tab: day length, water/electricity shutoff, night darkness, the helicopter event, meta events, generators, house alarms, and the mini-map/world-map toggles.
Designed to not fight the game:
- Only settings you actually change are written to
SandboxVars.lua— your sandbox preset's values and anything an admin tunes in-game stay authoritative for everything you don't touch. (This "differs-from-default" rule was hardened during live testing and now also protects the server-INI settings from v1.6.1.) - The file is generated from your Sandbox preset on first boot, so panel tweaks apply from the second start onward. "Re-apply preset on start" intentionally overrides them.
- Every setting name is validated in CI against a real game-generated
SandboxVars.lua, so a typo'd key can never silently ship.
Zomboid now has ~190 settings in the panel across World / Zombies / Loot / Survival / Vehicles / Server / PvP & Safehouses / Chat & Voice / Backups tabs — the deepest catalog of any supported game.
Upgrading
Standard image update, no manual steps. Existing Zomboid servers are unaffected until you change a sandbox setting.
