loopUnit:ChangeDamage(-5)
this makes 5 less damage (ie, healing)
So, you need to first check that the unit's owner is not the same as "playerID", and if this is true, check if the two players are at war, and if so, add 5
more damage to the "loopunit":
Code:
--------------------------------------------------------------
include("PlotIterators")
---------------------------------------------------------------
local iPromotionMasterRestorationMage = GameInfoTypes["PROMOTION_MASTER_RESTORATION_MAGE"]
function TES_MasterRestorationMage(playerID)
local player = Players[playerID]
local teamID = player:GetTeam()
local team = Teams[teamID]
for unit in player:Units() do
if unit:IsHasPromotion(iPromotionMasterRestorationMage) then
local plot = unit:GetPlot()
for loopPlot in PlotAreaSweepIterator(plot, 3, SECTOR_NORTH, DIRECTION_CLOCKWISE, DIRECTION_OUTWARDS, CENTRE_INCLUDE) do
for iVal = 0,(loopPlot:GetNumUnits() - 1) do
local loopUnit = loopPlot:GetUnit(iVal)
if loopUnit:GetOwner() ~= playerID then
local pOtherPlayer = Players[loopUnit:GetOwner()]
local iOtherTeam = pOtherPlayer:GetTeam()
if team:IsAtWar(iOtherTeam) and loopUnit:IsCombatUnit() then
loopUnit:ChangeDamage(5)
end
end
end
end
end
end
end
GameEvents.PlayerDoTurn.Add(TES_MasterRestorationMage)
As written it does not check for whether the player is a specific civ or not. Wasn't clear if that was needed.
There is a possibility that if the additional 5 damage pushes the unit over the '100' damage it takes to eliminate a unit you could get odd results or behaviors from the game. If that ends up being the case (I've never tried this exact scenario) then a simple check to see if 5 more damage will put the unit over the 'kill' knifeedge can be added to the code.

For the Combat % modifier thing:
Instead of trying to give them a combat % modifier (which as I recall is impossible directly via lua) I would give them a promotion. As I recall all you can do in lua is give a direct BaseCombatStrength or BaseRangedCombatStrength "change" as a direct integer value instead of a %. And then you have to be careful with your math and what that Base Combat Strength number has morphed to in order to not give the same effect multiple time to the same unit such that it suddenly has +50 BaseCombatStrength instead of +5. Promotions help automatically keep this under control because even if Unit-X already has Promotion-X, giving the same promotion to the same unit does not give double the promotion effect -- the unit can only have one copy of Promotion-X, regardless of how many times an lua method tries to add the same promotion to the same unit. So I would do something like as this (the code shown here is handiing both effects in one code):
Code:
--------------------------------------------------------------
include("PlotIterators")
---------------------------------------------------------------
local iPromotionMasterRestorationMage = GameInfoTypes["PROMOTION_MASTER_RESTORATION_MAGE"]
local iPromotionMasterAlterationMage = GameInfoTypes["PROMOTION_MASTER_ALTERATION_MAGE"]
local iPromotionAlterationMageAffect = GameInfoTypes["PROMOTION_X_SOMETHING"]
function TES_MasterRestorationMage(playerID)
local player = Players[playerID]
local teamID = player:GetTeam()
local team = Teams[teamID]
local tUnitsToGivePromotion = {}
for unit in player:Units() do
unit:SetHasPromotion(iPromotionAlterationMageAffect, false)
if unit:IsHasPromotion(iPromotionMasterRestorationMage) or unit:IsHasPromotion(iPromotionMasterAlterationMage) then
local plot = unit:GetPlot()
for loopPlot in PlotAreaSweepIterator(plot, 3, SECTOR_NORTH, DIRECTION_CLOCKWISE, DIRECTION_OUTWARDS, CENTRE_INCLUDE) do
for iVal = 0,(loopPlot:GetNumUnits() - 1) do
local loopUnit = loopPlot:GetUnit(iVal)
if loopUnit and (loopUnit ~= unit) then
if (loopUnit:GetOwner() ~= playerID) then
if unit:IsHasPromotion(iPromotionMasterRestorationMage) then
local pOtherPlayer = Players[loopUnit:GetOwner()]
local iOtherTeam = pOtherPlayer:GetTeam()
if team:IsAtWar(iOtherTeam) and loopUnit:IsCombatUnit() then
loopUnit:ChangeDamage(5)
end
end
else
if unit:IsHasPromotion(iPromotionMasterAlterationMage) and loopUnit:IsCombatUnit() and not loopUnit:IsHasPromotion(iPromotionMasterAlterationMage) then
table.insert(tUnitsToGivePromotion, loopUnit)
end
end
end
end
end
end
end
for Item,pUnit in pairs(tUnitsToGivePromotion) do
pUnit:SetHasPromotion(iPromotionAlterationMageAffect, true)
end
end
GameEvents.PlayerDoTurn.Add(TES_MasterRestorationMage)
"PROMOTION_X_SOMETHING" would then have the combat modifier as an intrinsic property of the promotion.
This line might have to be adjusted if you do not want a unit with either of the PROMOTION_MASTER_RESTORATION_MAGE or PROMOTION_MASTER_ALTERATION_MAGE promotions to have any possibility of getting the PROMOTION_X_SOMETHING promotion:
Code:
if unit:IsHasPromotion(iPromotionMasterAlterationMage) and loopUnit:IsCombatUnit() and not loopUnit:IsHasPromotion(iPromotionMasterAlterationMage) then
