Run a Lua function when game initializes

smellymummy · Nov 2, 2010

well is anyone else able to get that function to run at game init or is it just me?

Ryan F. Mercer · Nov 2, 2010

I tried running steam in compatibility mode Vista Service Pack 2 and selected directx 9 on game start. No luck. Also tried playing around with administrator privileges. Nada.

Mannu · Nov 2, 2010

I have the same firewall settings. I don't remember what else I did to get it working. Maybe it's a problem with your home network? I'm running a windows 7 home network.

I think I have a similar issue, I can get the test function working on game start but not my function (movesettlers) anybody knows why?

Code:

-- Lua Script1
--------------------------------------------------------------


local trackarg1 = nil;
local trackarg2 = nil;
local trackarg3 = nil;
local trackarg4 = nil;
local moveai = 0;


function utrack (arg1, arg2, arg3, arg4)

    trackarg1 = arg1;
    trackarg2 = arg2;
    trackarg3 = arg3;
    trackarg4 = arg4;

    local player = Players[ arg1 ];
    local unit = player:GetUnitByID( arg2 );
	local hx, hy  = ToGridFromHex( trackarg3, trackarg4 );
    local plot = Map.GetPlot(hx, hy);            
	unit:SetXY(hx, hy);

end


function validplot (pciv,unittag,arg1,arg2)
  
    valid = 0;
	iterations =0;
	local hx, hy  = ToGridFromHex( arg1, arg2 );
	
	local plot = Map.GetPlot(hx, hy);
	
	--not owned
	if ( not plot:IsOwned() ) then
	  --is passable
	  if ( not plot:IsImpassable() ) then
		--is land
		if ( not plot:IsWater() ) then
			--has no units
			if ( plot:GetNumUnits()==0 ) then
				valid=1;
			end
		end
	  end
	end
	print(valid);

	if (valid==0) then
	    --choose another random spot
		local iW, iH = Map.GetGridSize();
		--validplot (rand)
		posx = math.random (1,iW);
		posy = math.random (1,iH);		
		validplot (pciv,unittag,posx,posy);		
	else
		--order move unit		
		utrack (pciv,unittag,arg1,arg2);		
	end
end


function movesettlers ()
	    local player = Players[ 0 ];            
                for unit in player:Units() do                    					
					if (string.find( unit:GetName(), 'Settler') ) then
						local iW, iH = Map.GetGridSize();						
						--validplot (rand)
						posx = math.random (1,iW);
						posy = math.random (1,iH);
						validplot (0,unit:GetID(),posx,posy);
					end
                end            
end
Events.SequenceGameInitComplete.Add ( movesettlers );


function realstart ()
                print("Really really just started a game!");
end
--Events.SequenceGameInitComplete.Add ( realstart );

the settler doesnt exist at gameinit, its created after?

Ryan F. Mercer · Nov 19, 2010

Pretty smart for a smellymummy.

I bet that's it.

Incidentally, tho I haven't been able to get gameinit to output to the lua console, I thought I saw it mentioned in the lua code somewhere while I was looking for something else. Probably in InGame.lua. Anyway, tho I didn't look closely, I got the sense that the base files themselves call gameinit and the lack of an error suggests gameinit is functioning properly for the base files. <scratch head>

Maybe I'll try experimenting with it sometime today.

smellymummy · Nov 19, 2010

fairly sure init comes before the initial settler creation. easy to test with onunitcreated

but anyhow, since finding that gameinit crashes when using it in lua scripts loaded through entrypoints i'm just not using it at all anymore. instead, game initialization can be done with checks/loops/whathaveyou outside of functions so they are ran when the game loads up the lua for the first time

Ryan F. Mercer · Nov 19, 2010

I know you've posted it elsewhere, but would you be willing to post your alternative init control structure for the benefit of others reading this thread? I suspect a lot of us are going to be using it.

smellymummy · Nov 19, 2010

Code:

-- first let the game read in objects
local a = 0;

function init ()
    print( "Hello World!" );
end

-- now that those are processed, the script can use those 
if ( a == 0 ) then
    init();
end

I have found these two events that could be the ones you are looking for?

Event.GameplaySetActivePlayer
Launched sometime after all mods and game files are loaded. I think in single player it's only launched once, but that might change in multiplayer?

Event.LoadScreenClose
Launched after the user presses that "Begin your journey" button.

Hello,

PROBLEM DESCRIPTION
I have made a map script for multiplayers games. This script has some important additional setting in Advance Menu. I would like to show this setting to all players. I try to show it by popup windows with text description of all setting but I cant even lunch print function as Event at game start.

this is my code

Spoiler :

I try to use DisplayMessage by alpaca

	else
		AddButton(Locale.ConvertTextKey("TXT_KEY_CLOSE"))
	end
	ShowWindow()
end
LuaEvents.DisplayMessage.Add(DisplayMessage);

RESULT:
No popup window, no print result in LineTuner during singleuser tests. No error info. Nothing,

QUESTION:
1) Is it possible to add Events in map script?
2) How to transfer information about Advance Setting to all players. Maybe i can modify map details description?

Double check your VFS settings?

It's kind of the first question for just about anything it seems. Like that first line in the trouble shooting guide of any wall powered product: Is the unit plugged in?

Not what he means. Go into the mod's modinfo file, and check if the files in question have
import="1"
instead of
import="0"
for any Lua files that override existing logic. In ModBuddy, you can check this in the Properties window (it'll be true/false there with a pulldown), but the modinfo file is how you'd show us if it's working.

but it is a map script not a mod. I dont use ModBuddy

map script file is just copied to maps folder
Is it possible to add event from map script level?

I don't think so. They get processed at a point well before the game has fully initialized, so I don't think you can get a popup-type event to work inside them. A lot of things are like that.
Map scripts can have altered versions of existing Lua functions, which will override the core game's versions. One of the more annoying bits is that maps also override mods; if my mod has changed AssignStartingPlots.lua, and the map script has its own variants of the resource distributions, then it'll use the map's version in preference to my own (which to me is backwards). But that's VERY different than triggering a new event.

And you don't need ModBuddy for ANY mods, really. All ModBuddy does when it "compiles" is copy all of your files to a Mods directory and create a .modinfo text file, which you can adjust by hand. It's not an actual software compiler; the only complex parts of the modinfo file are the checksum bits, AFAIK. So the fact that a map script can be done without it doesn't really mean much.

I think the same way, you can't add event from map script level.

I don't need ModBuddy. It is easier just to copy newmap.lua file to maps folder. We use it only for multiplayer games and mods unfortunately are blocked in multiplayer so ModBoddy is useless for me.

EDIT:
i have found the solution of my problem:
player:AddNotification(NotificationTypes.NOTIFICATION_DIPLOMACY_DECLARATION, ScripSetText , "Map setup description...", plotX, plotY);

Code:

-----------------------------------------------------------------------------------
	-----------------------------Map settings info-------------------------------------
	-----------------------------------------------------------------------------------
	local IronHorse_useroption = Map.GetCustomOption(9);
	if IronHorse_useroption == 7 then
		ScripSetText = ScripSetText .. " IronHorseQty=Random";
	else
		IronHorse_useroption = IronHorse_useroption + 1;
		ScripSetText = ScripSetText .. " IronHorseQty=" .. IronHorse_useroption ;
	end
	
	local Uranium_useroption = Map.GetCustomOption(3);
	if Uranium_useroption == 1 then
		ScripSetText = ScripSetText .. " UraniumQty=None";
	end
	if Uranium_useroption == 2 then
		ScripSetText = ScripSetText .. " UraniumQty=Rare" ;
	end
	if Uranium_useroption == 3 then
		ScripSetText = ScripSetText .. " UraniumQty=Balanced" ;
	end

	for player_ID = 0, GameDefines.MAX_MAJOR_CIVS - 1  do
		player = Players[player_ID];
		if ( isValidPlayer(player) and player:IsHuman() == true ) then
			local CivName1 = player:GetName();
			playerStartPlot = player:GetStartingPlot();
			plotX = playerStartPlot:GetX();
			plotY = playerStartPlot:GetY();
			local playerteam_ID = player:GetTeam();
			local lineQty = 1 ;
			local areaID = playerStartPlot:GetArea();
			local area = Map.GetArea(areaID);
			local numTiles = area:GetNumTiles();
			ScripSetText = ScripSetText .. " AreaTitles=" .. numTiles .. "                                                ";
			for i = 0, GameDefines.MAX_MAJOR_CIVS - 1  do
				if i ~= player_ID then
					local playerProx = Players[i];
					if isValidPlayer(playerProx) then
						local playerProxteam_ID = playerProx:GetTeam();
						if playerProxteam_ID ~= playerteam_ID then
							local playerProxStartPlot = playerProx:GetStartingPlot();
							local plotX2 = playerProxStartPlot:GetX();
							local plotY2 = playerProxStartPlot:GetY();
							local ProximityToPlayer = Map.PlotDistance(plotX, plotY, plotX2, plotY2);
							
							if (ProximityToPlayer > 0 and lineQty < 6 ) then 
								local CivName2 = playerProx:GetName(); 
								if mirrordebug == 1 then
									print(">>>> ProximityToPlayer:",ProximityToPlayer,CivName1,CivName2);
								end
								lineQty = lineQty + 1;
								ScripSetText = ScripSetText .. " " .. CivName1 .. "<-->" .. CivName2 .. "=" .. ProximityToPlayer .. "                                   ";
							end
						end
					end
				end
			end
			if(ScripSetText ~= nil) then
				if mirrordebug == 1 then
					print(">>>> ScripSetText:",ScripSetText);
				end
				[B]player:AddNotification(NotificationTypes.NOTIFICATION_DIPLOMACY_DECLARATION, ScripSetText , "Map setup description...", plotX, plotY);[/B]
			end
		end
	end

its work ok and I can send info about map script setup this way
