[LUA] Use a return by a LUA-function in a new function

[martijnaikema]

Hi,

I have a basic LUA-question. I have a LUA-function "CalculateTraitGold" which returns two values:

return iPlayerID
return iTraitGold

Say I have a new function "UpdateTraitGold" which needs to add the iTraitGold to the player with ID iPlayerID. How do I need to set this function?

Shoud it be:

function UpdateTraitGold ()
CalculateTraitGold()
iPlayerID:ChangeGold (iTraitGold)
end

And if I set the Serial Events, which function(s) should I add? I guess only the UpdateTraitGold-function? Because it calls the CalculateTraitGold-function?

If you are returning 2 values you should do it in a single statement. i.e.

function CalculateTraitGold()
 -- whatever
 return iPlayerID, iTraitGold
end

Then the other function would look something like

function UpdateTraitGold()
 local iPlayerID, iTraitGold = CalculateTraitGold()
 Players[iPlayerID]:ChangeGold(iTraitGold)
end

I would agree that UpdateTraitGold() would be the function to add as the event handler.

I tried this but I can´t get it to work.

Here are both functions. Maybe you can have a look at what I am doing wrong

Spoiler :

function CalculateTraitGold()

iTraitGold = 0
iCivsTotal = Game:CountCivTeamsAlive()

for index,mPlayer in pairs(Players) do
if mPlayer:IsAlive() then
if (mPlayer:IsMinorCiv() or mPlayer:IsBarbarian()) then
else
if mPlayer:GetCivilizationAdjectiveKey() == "TXT_KEY_CIV_DUTCH_ADJECTIVE" then
iPlayerTraitID = mPlayer:GetID()

if iCivsTotal > 24 then
iTraitGold = 1
elseif iCivsTotal < 13 then
iTraitGold = 3
else
iTraitGold = 2
end

iEra = mPlayer:GetCurrentEra()
if iEra < 2 then
iMultiplyGold = 1
elseif iEra > 3 then
iMultiplyGold = 3
else
iMultiPlyGold = 2
end

iTraitGold = iTraitGold * iMultiplyGold

iCivsMet = Teams[mPlayer:GetTeam()]:GetHasMetCivCount()
iCivsAtWar = Teams[mPlayer:GetTeam()]:GetAtWarCount()
iCivsAtPeace = iCivsMet - iCivsAtWar

iTraitGold = iTraitGold * iCivsAtPeace

print (iPlayerTraitID)
print (iTraitGold)
return iPlayerTraitID, iTraitGold


end
end
end
end

end -- function

And the function to use the returns:

Spoiler :

function UpdateTraitGold ()
local iPlayerTraitID, iTraitGold = CalculateTraitGold()

print (iPlayerTraitID)
print (iTraitGold)

Players[iPlayerTraitID]:ChangeGold(iTraitGold)
end

And the Event Handler:

Spoiler :

Events.SerialEventGameDataDirty.Add(UpdateTraitGold);
Events.SerialEventTurnTimerDirty.Add(UpdateTraitGold);
Events.SerialEventCityInfoDirty.Add(UpdateTraitGold);

UpdateTraitGold();

I now noticed the runtime error in FireTuner:
Runtime Error: [string "Assets/UI/InGame.lua"]:1063: attemp to index local 'addinFile' (a nil value)
Runtime Error: Error loading Assets/UI/Ingame/InGame.lua

Here are my Mod Buddy setting

2 files:
GoldTrait.lua - tried both Import into VFS true and false
GoldTrait.xml

Actions: -
Content: InGameUIAddin - GoldTrait.lua

I am not using any subfolders in the MOD

 

[alpaca]

Try re-entering the content line. VFS has to be set to true for both files

 

[martijnaikema]

For both the xml and the lua file?

 

[alpaca]

For both the xml and the lua file?

Yes, if you use the xml at all.

 

[martijnaikema]

I use it for the TopPanel. I did not include the code cause it is not finished yet.

 

[martijnaikema]

Tried it but still the same error. I still need the InGameUIAddin in the Content-tab right?

Edit: I even tried a simple test.lua file to lead. It only contained print ("Hello World").

I got the same error :S

Yes. I don't know what's up, something like this works fine for me after I set VFS to true.

I might do a re-install of the game then

That sounds a bit drastic. I would try creating a new mod first, with a hello world lua script just for testing.

I know

But I did test it in a new MOD with the "Hello World" print. Still the same error. Also tried to clear the Cache of the game, but nothing seems to work.

It seems like, judging to the error, that the game is trying to add a file that does not exist. I also saw robk was having the same error in this thread:
http://forums.civfanatics.com/showthread.php?t=403062

But I can't relate his sollution to my problem.

 

[alpaca]

Well I got that error, too, but it disappeared after I set the VFS flag to true. Meh

 

[martijnaikema]

I did a re-install of the game and the SDK. Got it working now.
