[Lua] Spawn a unit without AddFreeUnit?

Irkalla · Jan 20, 2013

Basically, I want to spawn a unit that gets experience from Barracks and stuff. Any ideas?

What's wrong with InitUnit() and then Set/ChangeExperience()?

InitUnit spawns a unit at the given coords apparently? Funny name they chose.

I take it, to spawn a booty warrior at Player 1's capital in this manner... Let's assume I've got a working function that looks at the city's military training buildings, if any, and returns a function... I do:

Code:

local pPlayer = Players[0];
local iUnitID = GameInfoTypes["UNIT_BOOTY_WARRIOR"];
local pCapital = pPlayer:GetCapitalCity();
local pCapitalPlot = pCapital:Plot();

pSoldier = pPlayer:InitUnit( iUnitID, pCapitalPlot.X, pCapitalPlot.Y ); 
pSoldier:JumpToNearestValidPlot(); 
pSoldier:SetExperience( fnGetMilitaryTrainingXP( pCapital )

Sounds right, anyway. Should I set Experience before Jumping to Nearest Plot?

Pretty much. Although if you want to use a city as the generation point, something like

Code:

local sUnitType = "UNIT_WARRIOR"
pUnit = pPlayer:InitUnit(GameInfoTypes[sUnitType], pCity:GetX(), pCity:GetY())
pUnit:SetExperience(pCity:GetDomainFreeExperience(pUnit:GetDomainType()))
-- Could also use pCity:GetFreePromotionCount() to text for any free promotions from Wonders
pUnit:JumpToNearestValidPlot()
-- TAKE CARE!!! The unit may have just been deleted if there is no valid plot

Wow, you can do the experience thing? Well gently caress me!

Also, any idea as to in what situations JumpToNearestValidPlot() may fail?

It will only jump within the current area, so if you have a city on an island, and there are already units on every tile of that island it will fail.

So it won't put two units on the same tile then force you to move stacked unit? :T Sounds dumb.

Any alternatives for placing it that allows stacking?

Oh, also. Can I do that handle thing with AddFreeUnit instead of InitUnit?

Last thing, do you know anything about Notifications? Like, how can I change the icon of it and make it do that thing where you click it and it goes to a certain plot?

Just create the unit and don't use the Jump...() method - you'll end up with stacked units you'll have to move before you can end the turn - the problem is if the AI ends up with stacked units it can't move.

If you mean pUnit = Add... then yes

Yes. To change the icon you'll need to use one of the notification replacing mods, to do the click to jump to a plot you'll either have to use a standard notification that does that (eg a unit or wonder one) or use one of the notification replacing mods

Last thing... say I make a var pointing to a function (what are these actually called?)... How can I execute the function contained within? You know, so I can execute it then pass stuff on it.

Also, I'm thinking of doing this. A nice for loop that cycles through all cities. For each city, it counts all the player's units, initializes the unit meant to be created, jumps him to a valid plot, then counts all the player's units again. If second count == first count + 1, break.

In other words, check to see if it fails, then go to the next city and try it again until we get it.

JumpToNearestValidPlot() now returns a boolean, true if the unit was jumped, false if it was killed

Function pointers usually

Code:

local pFunc = Players[iPlayer]:GetCapital -- Note the lack of brackets
local pCapital = pFunc() -- Note the brackets

The no brackets is so you state pass args using the pointer, right?

Yeah, and for the above example, say instead of InitUnit I used AddFreeunit. Can I spawn the unit by just doing pUnit, then give him experience by doing pUnit:SetExperience(iXP)?

Loving A! So I can just do if pUnit:JumpToNearestValidPlot() then pUnit:JumpToNearestValidPlot(); break, else loop over to next city. Or will comparing it also run the function?

whoward69 · Jan 21, 2013

Correct, so it's just

if pUnit:JumpToNearestValidPlot() then break; end

Does GetFreePromotionCount() with no args test for any (*) free promotion? Whereas I can specify an arg to test for a specific promotion?

Nope.

GetFreePromotionCount() will tell you how many there are from the city (it returns an int), you then have to loop all possible promotions and then test IsFreePromotion(iPromotion) IIRC

This is what I finally ended up with after I go around to doing it. I'm mainly concerned about line 36. Is that how it's done?

Code:

[*]
[*]	--[[ On every growth of every city, run through the following list of conditions:

IIRC you'll need

for promotion in GameInfo.Promotions() do
local iPromotion = promotion.ID
-- other stuff
end

whoops. Still trying to get used to all this database structured query junk :lol:

Irkalla · Feb 23, 2013

I'm still hung up on this. Calling it a night.

Code:

if ( pCity:GetFreePromotionCount() > 0 ) then
    for promotion in GameInfo.UnitPromotions() do

	iPromotion = promotion.ID
								
	if pCity:IsFreePromotion( iPromotion ) then
		pFreeUnit:SetHasPromotion( iPromotion, true )
	end

    end

end
