	Help with Unit.txt Enter the AD-FREE zone

I'm sure these questions have been asked before but I didnt see it in the mod resources. A lot of these came from Martin's flaglist, but it doesnt have much details. Can anyone explain what these unit fuctions do or where to find info on them?

CantMove - Is this like the immobile flag Solver was working on? can it still attack?

Ill just answer the ones im sure of.

quote: IsTrader

Used for Caravans and Freights. This basically adds them to the available trade caravan count once theyre built i think. I think the move points for these units specified how many are added to the count, freight has 3 movement so 3 added to the available trade pool. That part is a guess though, i havent tested it.

quote: NeedsNoSupport

Well its just used for cities.

quote: CreateParks

This is used to specify which units can use the nanite cleansing attack on a city, which destroys the whole city. Only the eco-ranger has it in the unmodded game.

quote: CanInjoin

This is used for units that can file injunctions (stop production for 1 turn), only the lawyer can do it in the unmodded game.

quote: IsSpecialForces

Its used for special forces units, Samurai, Knights, Marines etc, when you lower military readiness the special forces units stay "at war" and cost full support all the time. If its used under other units like stealth etc then its so they always take full support cost all the time too.

quote: GovernmentType

This says which government the unit can only be built under. Fascist under Fascism, Televangelist under Theocracy etc.

quote: SettleBuilding - does this build time imp? and can you do it AI civs

This just allows when you use that unit with this flag (only the urban planner has it in unmodded game) when they found a new city the specified building is auto-built in that city.

code:
   SettleBuilding IMPROVE_ACADEMY
   SettleBuilding IMPROVE_COURTHOUSE
   SettleBuilding IMPROVE_GRANARY
   SettleBuilding IMPROVE_SHRINE
   SettleBuilding IMPROVE_THEATER

A lot of the unused ones are hangovers from C:CtP, and probably don't work, if indeed they ever did.

quote: AssistedDrops

Used by the Swarm unit in C:CtP. Offhand I can't think of any ability that was unique to the Swarm that would count as an Assisted Drop. Although it presumably relates to the space layer and is now redundant.

quote: SettlerSlaveRaids

CtP2 flag that lets a slaver pick off unescorted settlers.

quote: NotAffectedByLandMines

Somewhere in the early stages of C:CtP's programming they apparently toyed with the idea of landmines. Presumably they'd work in the same way as the Cow unit did, except with explosions rather than food. I would *guess* that the unaffected unit(s) would the Sweeper unit (unused sprite #37 in CtP1) and maybe some future-age tanks or something. Either way, the whole lot got scrapped, presumably since landmines were too easy to exploit, or too hard to program the AI around.

quote: BonusFood CanRustle

Cow-unit hangers-on from C:CtP. The intention being that cow units in a city radius would provide the city's food, and the rustler unit would come along and snaffle them, much in the same way a slaver would take a settler, although hypothetically the cow unit would just switch to the rustler's civ's ownership rather than being disbanded. This concept was also scrapped, probably due to similar reasons as the landmines.

quote: CreateRift

The C:CtP DEFAULT_SPRITE for a city is apparently a RIFT_GATE in units.txt, but of course this is superceded by the citysprite.txt so isn't used. There may be other references elsewhere, I forget. Either it's something to do with the wormhole probe victory, or another scrapped concept with space teleportation or something. We still don't know what the unit in Martin's avatar was meant to do/be. (Note the game one has blue stripes not red)

quote: CanCloak

The "Phantom" spaceship in C:CtP could cloak- basically it became a stealth unit, but could still attack. I can't remember how it affected zones of control (if at all). Doubt if it works in CtP2.

quote: TransformPartial

Appears to be completely unused. No idea.

quote: ShieldHunger FoodHunger

SheildHunger is the flag the game uses to calculate upkeep as far as I know. The FoodHunger flag is pretty hard to test, but I don't think anyone has had any success making it work.

quote: BRange - IS this bombard Range? Doe sthis mean we can do ranged artillery bombardment like civ3?

Unfortunately not.

quote: CantMove - Is this like the immobile flag Solver was working on? can it still attack?

I'm pretty sure Locutus tried this while making the militia code without success. It would be pretty cool to have a working one though.

Thanks IM and Maq

Just hope maybe some coders get them worker and maybe add some new ones...

another question though

I guess that means a spy unit with an attack value cant attack. I'd test if I had my computer, but I thought somewhere that it could and you wouldnt know who did it.

	Remove this text

I think it's the IsCivilian flag that prevents attacking (though the CantCaptureCity flag is probably a good one to disable as well if you want it to be a stealthy military unit). If you're attacked by a stealthy unit (EcoWarriors for example have attack values and stealth), it will show up anyway in the battle view, surely? I don't know what would happen if it attacked in a situation where the battle view was off.

Probably the ability of a unit to turn a oiece of land into a rift. But is probably unimplemented as well.

The production support costs for this unit per turn.

Probably the same but for food, possibly unimplemented.

Maybe this is the purpose, but I doubt that this is implemented.

FoodHunger is never used in the source, so I think it's safe to assume it does nothing.

Well, in theory, of course, all of them can be made to do something. I have looked at a couple and seen no half-finished chunks of code or anything like that, but there might well be in some.

I'm happy to go investigating some in particular if there are any you're especially curious about, but investigating the whole list seems a little daunting .

Thanks J,

Actually I'm just curious about a few "maybe simple" things like:

making hungerfood work

seeing if its possible to copy/edit hungershield into a hungergood function

looking at the settlecity code and see if it can be made into a settleimprov code so a unit when it settles builds a specified improvement

So most are seeing if original code can be copied and then modified to do a few new things


For an original one I was wonering if there is a way to take the POW SLIC used in conquests that creates captured units and make it into a unit function but with a 33% or 50% chance of success and the possibility of typing after the function POW in unit.txt what kind of unit is created i.e.
POW Unit_Fascist so 33% or 50% of the time when this unit wins a battle it would create a fascist. the other option would be that when POW is not followed by a specified unit, then it just changes the ownership of the unit captured i.e.
POW
If an infantry captures another infantry it stays an infantry instead of becoming a facsist or something.

Hope that doesnt blow you away J. I've been goin through SLIC but I'm no programmer but if I think I see the unit files in:

ctp2_code\gs\gameobj

But I couldnt make sense out of it. But I did see the "include" part in the beginning and I'm also wonder if we include tileimp and wonder files then we might be able to apply abilities/functions associated with tile imps and wonders to units?

thanks

It wouldn't be as simple as that, no. Although FoodHunger shouldn't be so hard to implement as ShieldHunger, it's surprisingly different, and it would have to be pretty much written from scratch. I might have a go, if I feel in the mood to, but no promises .

quote: looking at the settlecity code and see if it can be made into a settleimprov code so a unit when it settles builds a specified improvement

You mean tile improvements? I'm not really sure how that would work. Do you mean improvements on the city square or around it? If the latter, how would you decide where to put them, and which ones to use?

Is there anything in particular wrong with the existing SLIC, or are you just wanting it to go a little bit faster, or be easier to implement?

Sorry, I don't understand you...

	Tired of ads?

It looks like this code looks to see if a unit has the hungershield flag and then looks for the value after it and then subtracts that value from the players PW.

So it looks like that in order to fix hungerfood or add hungergold, we'd have to create the flag and then look for the number value after the flag...

Also the unit support code I listed previously doesnt mention hungerfood which may be why the flag appears unimplemented

code:

sint32 Unit::GetShieldHunger() const

{
    return GetDBRec()->GetShieldHunger(); 
}

sint32 Unit::GetFoodHunger() const

{
    return GetDBRec()->GetFoodHunger();

Is there an empire-wide food variable? I thought it was city based. If so, where would you deduct the food from?

There is no such variable. That's why I said it would be a big job - you'd have to comprehensively rework the way food is handled.

Would it be coprehensive to have the system look for the city with the highest excess food first and subrtract from it until it was no longer then subtract from the next highest one.

Basically a function that checks for the city with highest bonus, subtracts, checks again, subtracts, etc until either all are supplied or there is no bonus food left...

This system reminds me of Civ2, a city based instead of a empire wide based system, however maybe that could achieved over the food coefficent from the government stuff, or somewhere a function that calls us how many food must be deducted from each city.

Something like:

Needed food by units / number of cities and then substract it from all cities.

i think I like that idea for food better Martin. I think this highlights a bigger issue with food though, that there is no distribution system that models a real world situation. Like egypt was rome's bread basket and Rome grew based on food imports, likewise with the midwest. I guess a future issue, probably in governor.cpp, would be able to shift food (maybe also with the trade route system)

As for gold, its managed empire-wide so it shouldnt be as hard to implement right?


I think I hould open this up in a new thread, in the source code...
