ORP - Offline Raid Protection

ORP - Offline Raid Protection

Server-side PvP mod. No new items, no map changes, works on every map. Nothing for players to install or learn.

Tired of logging in to a wiped base because someone raided you at 4 AM? ORP makes an OFFLINE tribe's base a bad target while online tribes still fight normally. It does not make bases invulnerable - it makes attacking an empty base expensive and noisy, so raiders go find someone who is actually home.

What it does

When every member of a tribe has been offline for 30 minutes, that tribe becomes protected:

• Auto, Heavy and Tek turrets deal 3x damage (TurretDamageMultiplier)
• Structures take 1/3 damage (StructureDamageTakenMultiplier)
• Structures inside caves get an extra multiplier, so cave-camping stays honest (CaveStructureDamageMultiplier)
• Tames take half damage from player weapons: snipers, compound bows, rockets and more (TameDamageTakenMultiplier)
• The tribe gets an in-game raid alert (tribe alarm) and a tribe log entry when their base is hit, at most once per 5 min (RaidAlertCooldownSeconds)

Anti-abuse: protection can't start if the base was in combat in the last 30 minutes, so logging off mid-fight doesn't save you.

Ends instantly: protection stops the moment any tribe member logs back in - turret damage and resistances are reverted immediately.

• Works alongside ARK's own PreventOfflinePvP setting.
• Server-restart grace period, so nobody is instantly "offline" after a reboot.
• Solo players get the same protection as tribes.
• Lightweight: one scan every 30 s (about 3-4 ms for 300+ structures).
• Vanilla-safe: it changes numbers on existing turrets, structures and tames and puts them back. No replaced classes, so it stacks with other mods.

What it does not do

• It does not stop damage entirely. Determined raiders can still get in - it just costs a lot more.
• Turret range, targeting and ammo are unchanged; only damage per shot.
• Alliances don't count as "online" for each other.

Admin configuration

Add this block to your server's GameUserSettings.ini and restart. Missing keys use these defaults:

[OfflineRaidProtection]
OfflineDelaySeconds=1800
TurretDamageMultiplier=3.0
StructureDamageTakenMultiplier=0.3333
TameDamageTakenMultiplier=0.5
CaveStructureDamageMultiplier=6.0
RaidAlertCooldownSeconds=300
CombatCooldownSeconds=1800
StructurePollSeconds=30
DebugPrint=False

• OfflineDelaySeconds: how long the whole tribe must be gone (1800 = 30 min).
• TurretDamageMultiplier: 1.0 disables the turret buff.
• StructureDamageTakenMultiplier / TameDamageTakenMultiplier: 1.0 disables; 0.1 = very tanky.
• CombatCooldownSeconds: 0 disables the anti-abuse delay.
• StructurePollSeconds: lower = faster reaction, slightly more CPU.
• DebugPrint=True logs protection changes (leave off in production).

Raid alerts on Discord / phone

The raid alert uses ARK's tribe alarm, so it also goes through the vanilla AlarmPostNotificationURL setting in [ServerSettings]. Point it at a webhook bridge and players get raid alerts outside the game.

Compatibility

• Any map, official or modded.
• Stacks with other structure and turret mods.
• PC dedicated servers and single player. Cross-platform will follow once the PC release is stable.

Please report bugs in the comments with your [OfflineRaidProtection] settings and which map/mods you run.
