Resources not connecting to Trade Network

[sukritact]

I've been trying to make an ability where mines have a chance of discovering metal-type luxury resources.

I've managed to make the resource appear but it's not connecting to the trade network; so the player doesn't actually receive the resource. They just get a mine with Gold/Silver/Copper in it. I can't figure why it's so or how I could fix this.

I've just been triggering Plot:SetResourceType on GameEvents.BuildFinished. But here's the relevant function:

local iMine = GameInfoTypes.IMPROVEMENT_MINE

function MineDiscovery(iPlayer, iX, iY, iImprovement)
	local pPlayer = Players[iPlayer]
	if (pPlayer:IsMinorCiv()) or (pPlayer:IsBarbarian()) then
		return
	end
	if (iImprovement ~= iMine) then
		print("not mine")
		return
	end
	
	--Must be in woking distance of a city you own
	local bStop = true
	local pPlot = Map.GetPlot(iX, iY)
	for pAdjacentPlot in PlotAreaSweepIterator(pPlot, 3, SECTOR_NORTH, DIRECTION_CLOCKWISE, DIRECTION_OUTWARDS, CENTRE_INCLUDE) do
		if pAdjacentPlot:IsCity() then
			local pCity = pAdjacentPlot:GetPlotCity()
			if pCity:GetOwner() == iPlayer then
				bStop = false
				break
			end
		end
	end
	if (bStop) then
		return
	end
	
	local iPercentage = GetPersistentProperty("iPercentage_P" .. iPlayer)
	iRandom = math.random(1,10)
	print(iRandom, iPercentage)
	if iRandom > iPercentage then
		print("Percentage failed")
		return
	end
	if pPlot:GetResourceType() ~= -1 then
		print("Resource failed")
		return
	end
	
	pPlot:SetResourceType(iLuxury, 1)
	iPercentage = iPercentage - 1
	if iPercentage < 1 then
		iPercentage = 1
	end
	
	SetPersistentProperty("iPercentage_P" .. iPlayer, iPercentage)
end

GameEvents.BuildFinished.Add(MineDiscovery)

It's because there was no resource there while the build was finished. It seems like game is updating resources only on build/destroy.

Anyway, one of the possible solutions should be to recreate mine.
1) Set Improvement pillaged and repair it.
2) Remove improvement, add resource, add improvement.
3) Etc.

If this is not working, you may try:
-remove improvement
-add resource
-set build to almost done, so worker would finish it in next turn (it would make it +1 turn buildtime in exchange of resource)

I think that you can also iterate through all Cities owned by Player in order to check the distance.

Yes; that seems to be it. Thank you!

If you change the resource on an owned tile, while the visual changes the connected resource does not. Basically you have to remove the tile from being worked by the city (if necessary), set the owner of the tile to nobody, change the resource, change the ownership back, set the tile being worked (if necessary) and then add the improvement.

Look in IGE for the actual code to do this.
