Time & Weather Control

How to freeze/set the world clock and force weather from a mod (verified against 7DTD 3.0 decompile, July 2026; used by zPhone's God-app "Clear Noon" toggle).

Freezing / advancing time

• The clock is advanced by GameManager.updateTimeOfDay(), which reads GameStats.GetInt(EnumGameStats.TimeOfDayIncPerSec). Setting it to 0 freezes time-of-day (vanilla still calls world.SetTime(world.worldTime) every 100 ms to keep clients synced).
• Default value is derived in GameModeAbstract.Init: TimeOfDayIncPerSec = 24000 / (DayNightLength_minutes * 60). Restore a frozen clock by recomputing this from GamePrefs.GetInt(EnumGamePrefs.DayNightLength) — don't cache the old value.
• It is re-derived at every world start, so a persistent freeze must be re-applied after world load (zPhone uses a once-per-second enforcer MonoBehaviour).
• Set an absolute time with world.SetTime(day * 24000UL + hour * 1000UL). One game day = 24000 ticks, noon = 12000.

Forcing weather

Static fields on WeatherManager; sentinel values mean "not forced":

Field	Off value	Notes
forceClouds / forceRain / forceSnowfall / forceWind	-1f	0..1 range
forceTemperature	-100f	°F. Rain falls as snow at ≤ 32

• WeatherManager.BaseTemperature is a public const = 70 (°F) — the "default forest" baseline temperature.
• After changing force fields set WeatherManager.needToReUpdateWeatherSpectrums = true and call WeatherManager.Instance.CloudsFrameUpdateNow() so the sky updates immediately.
• WeatherManager.Cleanup() resets all force fields on world exit — same re-apply caveat as the time freeze.

Blocking status effects (buffs) on the player

All status effects (bleeding, infection, broken limbs, stun, food/water debuffs) route through EntityBuffs.AddBuff(string, ...). A Harmony prefix returning false when __instance.parent is EntityPlayerLocal blocks them at the source — removing after the fact via RemoveBuff does NOT undo the buff's onAdded triggers, so block in the prefix. Resolve the method with a reflection TargetMethod() (first AddBuff overload whose first param is string) because TFP has shipped several signature variants — see the pattern in "Harmony Patching". Implementations: zPhone GodNoStatusChange.cs, Scepters BuffPatch.cs.
