Function for a Live Tuner Panel

[GeneN]

I would like to create a custom function and access it from a live tuner panel. I have created a Lua file and can load it by identifying it as a <LoadStates> item in the ltp file. It initializes variables that I use in the live tuner panel and seems to work as expected. However, when I add a function definition to the Lua file the live tuner panel does not work as expected.

A pointer or two would be greatly appreciated!

Update: I changed the structure of the code in lua file referenced in <LoadStates> to 1) define variables, 2) define functions and then 3) call the function that initializes the variables. This structure makes the functions referenced in <LoadStates> accessible by code in the ltp file. ltp references:

  <CompatibleStates>
    <string>InGame</string>
    <string>_TunerResourcePanel</string>
  </CompatibleStates>
  <LoadStates>
    <string>_TunerResourcePanel</string>
  </LoadStates>

Referenced Lua code:

g_PanelHasFocus           = false
g_SelectedPlayer          = -1
efn_OnlyRevealedResources = true
efn_OnlyRevealedPlots     = true
efn_ResourceNames         = {}
efn_ResourceDataByName    = {}
efn_ResourcesToLocateList = {}
efn_ResourcePinData       = {}

-------------------------------------------------------------------------------

function efn_IsResourceRevealed(resName, player)
-- Function returns true iff the specified resource has been revealed to the specified player
   print("efn_ResourceRevealed entered")
   local idxTech, idxCivic, techRevealed, civicRevealed
   local resource = efn_ResourceDataByName[resName]
   idxTech  = resource.IndexPrereqTech
   idxCivic = resource.IndexPrereqCivic
   techRevealed  = (idxTech  == -1) or player:GetTechs():HasTech(idxTech)
   civicRevealed = (idxCivic == -1) or player:GetCulture():HasCivic(idxCivic)
   return techRevealed and civicRevealed
end

function efn_Initialize()
   print("_TunerResourcePanel loading")
   local resource, resourceName, prereqTech, idxPrereqTech, prereqCivic, idxPrereqCivic
   for resource in GameInfo.Resources() do
     resourceName = string.gsub(resource.ResourceType, "RESOURCE_", "")
     table.insert(efn_ResourceNames, resourceName)
     prereqTech = resource.PrereqTech
       idxPrereqTech = -1; if prereqTech then idxPrereqTech = GameInfo.Technologies[prereqTech].Index end
     prereqCivic = resource.PrereqCivic
       idxPrereqCivic = -1; if prereqCivic then idxPrereqCivic = GameInfo.Civics[prereqCivic].Index end
     efn_ResourceDataByName[resourceName] = {Index = resource.Index, IndexPrereqTech = idxPrereqTech, IndexPrereqCivic = idxPrereqCivic}
   end
   print("Initialized Resource Data Lists:")
   print("\tCount\t\tName\t\tIndex\tIndexReqTech\t\tIndexReqCivic")
   local idxRes, resourceData
   for idxRes, resourceName in ipairs(efn_ResourceNames) do
       resourceData =  efn_ResourceDataByName[resourceName]
       print("\t" .. idxRes .. "\t" .. resourceName .. "\t" .. resourceData.Index .. "\t" .. resourceData.IndexPrereqTech .. "\t" .. resourceData.IndexPrereqCivic)
   end
   print("**********************************")
end

efn_Initialize()

The function: "efn_IsResourceRevealed(resName, player)" is available in the ltp code.
