[ Tutorial ] How to add, not replace stuff in worldgeneration

Serpens · February 12, 2017

Hi

since I saw Lumina made a few tutorials, I thought I also might make a short one about adding new structures to worldgeneration, since the newest two mods I saw on workshop, made it the "wrong" way.
All code mentioned here belongs to modworldgenmain.lua.

In most mods you see, the author added his new trees or other structures like this in modworldgenmain.lua:

Spoiler


if GLOBAL.terrain.rooms.BGBadlands then
    GLOBAL.terrain.rooms.BGBadlands.contents.distributeprefabs.coffebush = 0.2
end
if GLOBAL.terrain.rooms.Lightning then
    GLOBAL.terrain.rooms.Lightning.contents.distributeprefabs.coffebush = 0.1
end
if GLOBAL.terrain.rooms.Badlands then
    GLOBAL.terrain.rooms.Badlands.contents.distributeprefabs.coffebush = 0.3
end
if GLOBAL.terrain.rooms.HoundyBadlands then
    GLOBAL.terrain.rooms.HoundyBadlands.contents.distributeprefabs.coffebush = 0.1
end
if GLOBAL.terrain.rooms.BuzzardyBadlands then
    GLOBAL.terrain.rooms.BuzzardyBadlands.contents.distributeprefabs.coffebush = 0.1
end

But this code REPLACES everything else in this area, instead of adding new stuff!

If you take a closer look in the game files, you will see that all "distributeprefabs" values are relative to each other.
So if you have 0.05 trees, 0.07 rabbits and 0.1 grass, this will result to a total value of 0.05+0.07+0.1 = 0.22
The result will be 0.05/0.22 = 22,72% trees. (of the chosen space)

If you now add your coffebush the way like above with value of 0.2, the total value will be 0.22+0.2 = 0.42
So now you will only get 0.05/0.44 = 11.36 % trees. (of the chosen space)

With more mods like this, the endresult will be like no trees at all, but only mod-things.

There is another important value you have to change, if you don't want to replace other things: distributepercent.
If "distributepercent" is for example 0.4 , this means at 40% of the available space, any thing will be placed. The rest of the space stays empty.
So if you make it 1, everything would be full of trees, rabbits, grass and other stuff, there would be no space left.
That means, if you add new things, you should also increase "distributepercent", to really add and not replace.

I developed a system for this in my "Increase Animals" mod:
http://steamcommunity.com/sharedfiles/filedetails/?id=758921911

The only thing I was not able to solve yet is, that "distributepercent" can't be more than 1 = 100% of course.
So if you play with 10 mods, all of them adding 10% of space things, they will still replace old stuff, as soon as the distributepercent value reaches 100%. But 10% is quite alot, a more common value would be ~1%. In additoin if you reach 100%, the whole space is cluttered with stuff, which is also not nice to play with

I extracted the code, so you can simply copy paste the following in your modworldgenmain.lua:

GLOBAL.require("map/terrain")

-- some math helpers
local function mymathclamp(num, min, max)
    return num <= min and min or (num >= max and max or num)
end
local function myround(num, idp)
    return GLOBAL.tonumber(string.format("%." .. (idp or 0) .. "f", num))
end

-- roomincrease is an array of the rooms where you want to add your prefab and a percentage how many.
-- {BGMarsh=0.8,Badlands=2,BGSavanna=1} this would result in 0.8% of the space in BGMarsh, 2% of space in Badlands and 1% of space in BGSavanna.
-- The percentage is percentage of total available space! I suggest at max 10, not more! A more common value would be ~ 0.8 The code does not allow values above 20.
local function AddThingtoWorldGeneration(prefab,roomincrease)
    local Increase = 0
    for roomstr,add in pairs(roomincrease) do
        Increase = add/100
        if Increase > 0 and Increase <= 0.2 then
            local oldpercent = 0
            local oldsum = 0
            local prefabvalue = 0
            AddRoomPreInit(roomstr, -- if the room does not exist, it is added... so in case we want to support mod rooms, we shoudl call all active rooms first, and test if this room is active at the moment
                function(room)
                    if room.contents then
                        oldpercent = room.contents.distributepercent or 0
                        if not room.contents.distributeprefabs or oldpercent==0 then
                            room.contents.distributeprefabs = {}
                            prefabvalue = 1 -- here this value does not matter, cause it is the only one
                            room.contents.distributeprefabs[prefab] = (room.contents.distributeprefabs[prefab] and room.contents.distributeprefabs[prefab] + prefabvalue) or prefabvalue
                            room.contents.distributepercent = Increase
                        else
                            oldsum = 0
                            for distprefab,number in pairs(room.contents.distributeprefabs) do
                                if type(number)=="table" then -- eg: smallmammal = {weight = 0.025, prefabs = {"rabbithole", "molehill"}},
                                    -- print("number ist eine table bei: "..tostring(distprefab).." in room: "..tostring(roomstr))
                                    for k,v in pairs(number) do
                                        -- print("k: "..tostring(k).." v: "..tostring(v))
                                        if type(v)=="number" and k=="weight" then
                                            oldsum = oldsum + v
                                        end
                                    end
                                elseif type(number)=="number" then
                                    oldsum = oldsum + number
                                end
                            end
                            room.contents.distributepercent = mymathclamp(oldpercent + Increase,0,1)
                            prefabvalue = myround((oldsum * (room.contents.distributepercent / oldpercent)) - oldsum,8)
                            room.contents.distributeprefabs[prefab] = (room.contents.distributeprefabs[prefab] and room.contents.distributeprefabs[prefab] + prefabvalue) or prefabvalue
                        end
                        -- print("Increaser Debug: "..roomstr..": added "..prefab..". oldpercent: "..oldpercent..", oldsum: "..oldsum..", newpercent: "..room.contents.distributepercent..", prefabvalue: "..prefabvalue..", newvalue: "..room.contents.distributeprefabs[prefab])
                    end
                end
            )
            print("Increaser: Add "..tostring(myround(Increase*100,2)).."% "..prefab.." to room: "..roomstr)
        elseif Increase > 0.2 then
            print("Increaser: Value of Increase is too high for "..prefab..", reduce it!")
        end
    end
end

After that, all you need is this line below my function:

AddThingtoWorldGeneration("coffebush",{BGBadlands=0.7,Badlands=1,Lightning=1.1,HoundyBadlands=0.5,BuzzardyBadlands=0.6})

The number value is percentage of total available space! I suggest at max 10, not more! A more common value would be ~ 0.8. If you would set 100 or the total of the same terrain sums up to 100, every single point on the map would contain your thing, so there would be no space left to even walk.

When adding new objects, don't forget to adjust the filters, so your object won't be on Roads for example. But that is already correct in all mods I saw:

GLOBAL.terrain.filter.coffebush = {GLOBAL.GROUND.ROAD, GLOBAL.GROUND.WOODFLOOR, GLOBAL.GROUND.CARPET, GLOBAL.GROUND.CHECKER}

At last some terrain names I collected for my Increase Animals mod, so you do not have to search in game files, which terrains does exist. Might be incomplete, but I think the most important ones are there. There is no need to include the following in your code, it is just meant as a list of terrain names that you could use. EDIT: I replaced the code style with just a normal list, so there will be no misundertstanding.

Spoiler

these are mostly used rooms I think
"BGBadlands","Badlands","Lightning","HoundyBadlands","BuzzardyBadlands","Moundfield",
"BGDeciduous","DeepDeciduous","DeciduousMole","DeciduousClearing","PondyGrass","MolesvilleDeciduous","MagicalDeciduous",
"BGGrassBurnt","BGGrass","MandrakeHome","GrassyMoleColony","FlowerPatch","EvilFlowerPatch","Waspnests","WalrusHut_Grassy","Walrusfield","PigTown","PigVillage","PigKingdom","PigCamp",
"BGDirt","BGNoise",
"BGCrappyForest","BGForest","BGDeepForest","BurntForest","CrappyDeepForest","DeepForest","Forest","ForestMole","CrappyForest","BurntClearing","Clearing","SpiderForest","SpiderCity","Graveyard",
"BGMarsh","Marsh","SpiderMarsh","SlightlyMermySwamp","SpiderVillageSwamp","Mermfield","Tentacleland",
"BGRocky","Rocky","GenericRockyNoThreat","MolesvilleRocky","BGChessRocky","RockyBuzzards","SpiderVillage","WalrusHut_Rocky","Tallbirdfield","TallbirdNests","PigCity",
"BGSavanna","Plain","BarePlain","WalrusHut_Plains","BeefalowPlain",

-- and here you see which mob belongs to which terrain I think

Spiders = {"SpiderMarsh","SpiderForest","SpiderCity","SpiderVillage","SpiderVillageSwamp","SpiderfieldEasy","Spiderfield",},
Wasps = {"BeeClearing","FlowerPatch","EvilFlowerPatch","Waspnests",}, -- everywhere were bees are
Merms = {"SlightlyMermySwamp","MermTown","Mermfield",},
Tentacles = {"BGMarsh","Marsh","Tentacleland",},
Walrus = {"WalrusHut_Plains","WalrusHut_Grassy","WalrusHut_Rocky","Walrusfield",},
Hounds = {"HoundyBadlands","Moundfield",},
Clockworks = {"ChessArea","MarbleForest","ChessMarsh","ChessForest","ChessBarrens","BGChessRocky","Chessfield",},
GuardPigs = {}, -- guardpigs have no natural room...

-- neutral
Bees = {"BeeClearing","FlowerPatch","EvilFlowerPatch","Waspnests",},
Tallbirds = {"TallbirdNests","Tallbirdfield",},
Beefalos = {"BeefalowPlain",},
Pigs = {"PigTown","PigVillage","PigKingdom","PigCity","PigCamp",},
Rabbits = {"BGSavanna","Plain","BarePlain",},
Moles = {"GrassyMoleColony","DeciduousMole","MolesvilleDeciduous","ForestMole","MolesvilleRocky",},
Voaltgoats = {"Lightning",},
Catcoons = {"BGDeciduous","DeepDeciduous","MagicalDeciduous","DeciduousMole","PondyGrass",}

If you think we can even improve my code, please tell me and I will make adjustments

Yes, you can argue that with all the mods adding new stuff, the world could get too full, if nothing is replaced.
But as you can see above, if everytime something is replaced, there might be nothing from the old stuff left in the end.
Of course feel free to develope another code system, that gets rid of both disadvantages!

I'll give it a try. I have some questions :

- This code goes in modworldgen.lua right ?
- Could i use both methods, part replace, part your code ?

- If i understand well, your code is more "stable" about the number of things added ? Like, if i set things on 0.8, i will not end with "ton in one biome, few in another" because it will no more be linked with what is already in theses biomes ? (Not sure i'm clear...)

- yes in modworldgenmain.lua.

- Yes, there should be no conflict using both methods. But keep in mind with the first "replacer-method" you have to look up at least all game values of that terrain, to keep the chosen value in line with them (according to calculation formula above). And you can't know those values of other mods....
And even if you would know all values, with enough mods active, you need to adjust values of game objects to keep balance... this might be a step to find code for a middleway.

- Yes, I chose the value to be "percentage of the total available space" instead of linking to other objects. So if you chose a value of 1 with my skript, 1% of the whole space in that area, whill contain this object, regardless of the number of other objects.

Very hard But a very interesting article!

I kind of knew how to do. The code will look like?

AddThingtoWorldGeneration("hole",{BGForest=0.015,BGCrappyFores=0.015})

AddThingtoWorldGeneration("tee_tree",{BGForest=0.9,BGCrappyFores=0.9})

AddThingtoWorldGeneration("wheat",{BGSavanna=0.18})

AddThingtoWorldGeneration("coffebush",{BGBadlands=0.7,Badlands=1,Lightning=1.1,HoundyBadlands=0.5,BuzzardyBadlands=0.6})

GLOBAL.terrain.filter.coffebush = {GLOBAL.GROUND.ROAD, GLOBAL.GROUND.WOODFLOOR, GLOBAL.GROUND.CARPET, GLOBAL.GROUND.CHECKER}
GLOBAL.terrain.filter.tee_tree = {GLOBAL.GROUND.ROAD, GLOBAL.GROUND.WOODFLOOR, GLOBAL.GROUND.CARPET, GLOBAL.GROUND.CHECKER}
GLOBAL.terrain.filter.wheat = {GLOBAL.GROUND.ROAD, GLOBAL.GROUND.WOODFLOOR, GLOBAL.GROUND.CARPET, GLOBAL.GROUND.CHECKER}
GLOBAL.terrain.filter.hole = {GLOBAL.GROUND.ROAD, GLOBAL.GROUND.WOODFLOOR, GLOBAL.GROUND.CARPET, GLOBAL.GROUND.CHECKER}

But What better figures put spawn in appearance. At your discretion?

Everything looks good, but when using your code it causes the server to fail to start. I'm only trying to add in one prefab to spawn at the moment.


GLOBAL.require("map/terrain")

-- some math helpers
local function mymathclamp(num, min, max)
    return num <= min and min or (num >= max and max or num)

            local oldpercent = 0

Thank you for taking the time and trying to implement it in your mod
Yes your code looks alright The values for coffebushes I put into my code example are just random numbers. They might fit your needs, but better try a bit around and see if the number of coffebushes is too less/to many.

English is not my native language. I know each word of both sentences, but I have no clue what you are asking =/
Could you try to ask it with other words or other sentence?

@Eusong:
If game crashes, the first thing you do, is looking at the logfiles. This is a general advise

IIn the logfile you should get at least the file and line of the crash. And that will help alot to find out what went wrong, since I do not see any mistake by looing at the code.
btw. the big list of all terrain types is not needed in the code. It was only meant to give you a list of what terrains do exist.

It looks to me like the issue is with the line "for roomstr,add in pairs(prefabslist) do"

@Eusong:
you can use the "spoiler" tag to shorten your post.
And yes, look for "lua error" in your code and you will find out that "prefablist" is nil, which means it is undefined.

As I wrote I extracted the code from my other mod, but adjusted it a bit to work on its own. I forgot to rename this variable.
Please replace it with "roomincrease", I will fix it in first post.
Thank you for finding this bug
I tested the code now and it should work now (no more bugs I think)

Ah, thanks, i got this error too but wasn't sure it was my mistake (since i tried to add it to my current worldgen), i didn't have time for more try at this moment. Good to know i wasn't alone and it's fixed now, i'll try it again soon then ^^

Eusong · February 12, 2017

Thank you! And sorry, I didn't realize there was a spoiler tag. xD

Thank you for taking the time and trying to implement it in your mod
Yes your code looks alright The values for coffebushes I put into my code example are just random numbers. They might fit your needs, but better try a bit around and see if the number of coffebushes is too less/to many.

English is not my native language. I know each word of both sentences, but I have no clue what you are asking =/
Could you try to ask it with other words or other sentence?

I mean: What is better to use numbers ? And English is also not my native language. I am Russian . According to this and there are errors in my text !

you want to know which numbers to use in my "AddThingtoWorldgGeneration" function?
The best would be to try around with different numbers. Try e.g 5 and see ingame how many are spawned. then try 0.5 and also 1 and see what you like best.
