Experimental: needs Dev CE (fork of the Community Extension, release zip and source). A GameCore that adds these Lua methods by calling engine functions directly. Not part of the upstream Community Extension, single-player testing only. Descriptions on these pages were written by an AI assistant from decompiled code and are marked inferred unless a test result confirms them.

BarbarianTribes

15 methods (Dev CE test build). this is found with the game's own IBarbarianTribes instance resolver (plain).

Method	Signature	Purpose (AI-written, inferred)	Tested	Engine function	Current
CanTribeTrainUnitNow	`BarbarianTribes:CanTribeTrainUnitNow(iTribeIndex: integer, eUnitType: integer) → boolean`	Checks whether a tribe can train a unit now: unit exists and is available, not blocked by a government flag, prerequisite tech is known by the player or the clan, and prerequisite civic is held.	plumbing ✓	—	`0xe20c0`
ChangeSpawnRate	`BarbarianTribes:ChangeSpawnRate(tribe: integer, rate: integer)`	Sets the warrior spawn rate of the given tribe.	plumbing ✓	—	`0xe2220`
CreateCamps	`BarbarianTribes:CreateCamps()`	Creates new barbarian camps: submits and runs AI camp-evaluation jobs, counts land plots and unseen ones to compute a target camp count, then places camps. Decompilation is truncated after the count logic, so placement details are not visible.	plumbing ✓	—	`0xe2270`
DoTurnActivate	`BarbarianTribes:DoTurnActivate(bFirstActivation: boolean)`	Per-turn clans update: if the clans capability is on and bFirstActivation is true, picks a random tribe whose conversion is at least 100 percent on a valid city-found location and converts it to a minor civ; then advances a counter and tries to let a tribe claim a unique unit. Output truncated at the end.	plumbing ✓	—	`0x620400`
GetBribeClanGoldCost	`BarbarianTribes:GetBribeClanGoldCost(iTribeIndex: integer, ePlayer: integer) → number`	Computes the gold cost for a player to bribe a barbarian clan: tribe definition base property plus a per-player factor, adjusted for game speed.	plumbing ✓	—	`0x6209b0`
GetCurrentEra	`BarbarianTribes:GetCurrentEra() → number`	Returns the game's current era, or the first era if none is set yet.	plumbing ✓	—	`0x620ab0`
GetHireClanGoldCost	`BarbarianTribes:GetHireClanGoldCost(iTribeIndex: integer, ePlayer: integer, eUnitType: integer) → number`	Computes the gold cost for a player to hire a clan with a given unit: unit production cost converted to purchase cost, multiplied by a global factor.	plumbing ✓	—	`0x620ae0`
GetPreviousCampDistanceFromPlot	`BarbarianTribes:GetPreviousCampDistanceFromPlot(iPlotIndex: integer) → number`	Returns the smallest plot distance from the given plot to any previous camp location in the stored list; 0 if the list is empty.	plumbing ✓	—	`0xe3f60`
GetRaidClanGoldReward	`BarbarianTribes:GetRaidClanGoldReward(iTribeIndex: integer, ePlayer: integer) → number`	Computes the gold reward for raiding a clan: barbarian camp improvement value plus a per-player amount, adjusted for game speed.	plumbing ✓	—	`0x620e00`
GetRaidScoreForTribe	`BarbarianTribes:GetRaidScoreForTribe(tribe: integer) → number`	Returns the tribe's raid score as the sum of two stored ints at offsets 0x78 and 0x7c.	plumbing ✓	—	`0xe4010`
GetRampageTarget	`BarbarianTribes:GetRampageTarget(tribeNumber: integer) → number`	Returns the player a tribe is currently rampaging against.	plumbing ✓	—	`0xe40a0`
GetTribeType	`BarbarianTribes:GetTribeType(tribe: integer) → number`	Returns the barbarian name type of the tribe at the index.	plumbing ✓	—	`0xe43f0`
GetUniqueUnitClaimTribe	`BarbarianTribes:GetUniqueUnitClaimTribe(eUnitType: integer) → number`	Looks up which tribe has claimed a given unique unit in the claim list.	plumbing ✓	—	`0x621090`
IsDefender	`BarbarianTribes:IsDefender(unitType: integer) → boolean`	Checks whether the unit type is in the barbarian defender unit list.	plumbing ✓	—	`0xe5090`
RemoveTribe	`BarbarianTribes:RemoveTribe(iTribeIndex: integer)`	Removes a tribe: finds the tribe with the given index, clears the improvement on its camp plot, updates two manager fields and marks the tribe entry as inactive.	plumbing ✓	—	`0xe5cd0`
