Trying to add newfoodtypes

[xovoxx]

Hello,

I'm trying to add a few new foodtypes to my mod. My endgoal is to have specific, existing items, and use them to feed a very picky NPC.

I am encountering an issue where my "constants.lua" file, the one where all the foodtypes appear to be, does not get overwritten by my mod.

I copied the "constants.lua" file in my mod's "scripts" folder, with the following additions : 

FOODTYPE =
{
    GENERIC = "GENERIC",
    MEAT = "MEAT",
    VEGGIE = "VEGGIE",
    ELEMENTAL = "ELEMENTAL",
    GEARS = "GEARS",
    HORRIBLE = "HORRIBLE",
    INSECT = "INSECT",
    SEEDS = "SEEDS",
    BERRY = "BERRY", --hack for smallbird; berries are actually part of veggie
    RAW = "RAW", -- things which some animals can eat off the ground, but players need to cook
    BURNT = "BURNT", --For lavae.
    ROUGHAGE = "ROUGHAGE",
	WOOD = "WOOD",
    GOODIES = "GOODIES",
    MONSTER = "MONSTER", -- Added in for woby, uses the secondary foodype originally added for the berries
	TIER2 = "TIER2",
}

(I only added the "Tier2" part, the rest was already there)

And further down : 

	TIER2 =
    {
        name = "TIER2",
        types =
        {
			FOODTYPE.TIER2,
        },
    },

Then, in the "gem.lua" file, I added the line : 

        inst.components.edible.foodtype = FOODTYPE.TIER2

However, when I'm trying to feed the red gem to the NPC, it won't accept it. This makes me believe that the new foodtype is not recognized by the gem prefab for some reason.

Can someone point me in the right direction?

Thank you!

@xovoxx You also have to modify the NPC's eater component to also accept your new food type.

see my comment here for an example:

but try to think carefully, how you could make your mod compatible to game updates and also other mods (since foodtpye seems to exclusive). Unfortunately, as written in my comment there, I don't have a good idea for that right now.

Right! I forgot to mention it in my post, but I did that.

I do it right after the NPC eats something else : 

local function OnEatFirstMeal(inst)
    inst.components.inspectable:SetDescription("He's not hungry anymore! Nice!")
	
    inst.components.eater:SetDiet({ FOODGROUP.TIER2 })
	if numberOfMeals == 0 then
		inst.components.inspectable:SetDescription("He looks better, but still hungry! He would love something shiny.")
	end
	if numberOfMeals == 1 then
		inst.components.inspectable:SetDescription("He's not hungry anymore! Nice!")
	end
	
	numberOfMeals = numberOfMeals + 1
end

Thanks for the reply! I'm not too worried about compatibility with other mods, I'm doing something really personal for close friends.

What I can see from your post is that writing
 

GLOBAL.FOODTYPE.NIGHTMAREFUEL = "NIGHTMAREFUEL"

in modmain declares this new foodtype, and then I can use it anywhere in my mod?

@xovoxx How is it supposed to be able to accept the new food type if it doesn't get set until after it eats it? 

You need to set the diet BEFORE.

I think you might be misunderstanding what I'm trying to do. I want to be able to feed it anything from its original diet, and THEN adjust its diet so it becomes more picky.

[penguin0616]

Yeah. You still have to set the initial diet.

Even if it's for an existing NPC? (I'm editing the moleworm)

Also, I added the following to my modmain : 

GLOBAL.FOODTYPE.TIER2 = "TIER2"

AddPrefabPostInit("gem",function(inst)
    inst:AddComponent("edible")
    inst.components.edible.foodtype = GLOBAL.FOODTYPE.TIER2
    inst.components.edible.healthvalue = 10
    inst.components.edible.hungervalue = 20
    inst.components.edible.sanityvalue = 5
end)

Which seems to work. However, this is still not working : 

local function OnEatFirstMeal(inst)
    inst.components.inspectable:SetDescription("He's not hungry anymore! Nice!")
	
    inst.components.eater:SetDiet({ FOODGROUP.TIER2 })
	if numberOfMeals == 0 then
		inst.components.inspectable:SetDescription("He looks better, but still hungry! He would love something shiny.")
	end
	if numberOfMeals == 1 then
		inst.components.inspectable:SetDescription("He's not hungry anymore! Nice!")
	end
	
	numberOfMeals = numberOfMeals + 1
end

What happens is this : 

- I feed the moleworm his usual meal (Since it has its usual diet, that I did not change).

- After feeding it once, it looks as if the game did not recognize my FOODGROUP.TIER2 constant, and the moleworm no longer eats anything.

Yep.

Okay... I'm not sure I understand what you're suggesting.

The mole.lua prefab already contains 

inst.components.eater:SetDiet({FOODTYPE.ELEMENTAL})

I did not remove it. What more am I supposed to do?

[penguin0616]

@xovoxx What did you mean by that it wasn't accepting the red gem?

 

[xovoxx]

@penguin0616

I'll try to rephrase what I'm trying to do. I'm probably not clear enough!

What I want to happen :

- Feed the moleworm any "ELEMENTAL" food once.

- Then, I want to be able to feed "TIER2" food, and only "TIER2" food, to the moleworm

What actually happens :

- I feed the moleworm any "ELEMENTAL" food once, successfully.

- Then, when I attempt to feed the red gem (A "TIER2" food item, thanks to the script in modmain) to the moleworm, the "feed" prompt does not show up.

- Additionally, any "ELEMENTAL" food is no longer accepted (the "feed" prompt does not show up).

 

Does that make more sense?

In your 
inst.components.eater:SetDiet({ FOODGROUP.TIER2 }), you have "FOODGROUP"

Everywhere else, you have "FOODTYPE"

That's my first guess as to why your issue exists.

[xovoxx]

/facepalm that couldn't have helped.

However, I fixed it and it doesn't work any better.

Is there a way to add this function to modmain? Instead of having it in mole.lua, where it currently is.

local function OnEatFirstMeal(inst)
    inst.components.inspectable:SetDescription("He's not hungry anymore! Nice!")
	
    inst.components.eater:SetDiet({ FOODTYPE.TIER2 })
	if numberOfMeals == 0 then
		inst.components.inspectable:SetDescription("He looks better, but still hungry! He would love something shiny.")
		SpawnPrefab("flowerhat").Transform:SetPosition(inst.Transform:GetWorldPosition())
	end
	if numberOfMeals == 1 then
		inst.components.inspectable:SetDescription("He's not hungry anymore! Nice!")
		SpawnPrefab("amulet").Transform:SetPosition(inst.Transform:GetWorldPosition())
	end
	
	numberOfMeals = numberOfMeals + 1
end

 

[penguin0616]

You shouldn't be replacing DST prefabs. That being said,

local function OnEatFirstMeal(inst)
	-- too lazy to copy your code
	-- also, you can use eater:TimeSinceLastEating() to figure out when they last ate.
end

AddPrefabPostInit("mole", function(inst)
	inst.eater:SetOnEatFn(OnEatFirstMeal) -- will now trigger whenever moleworm eats something
end)

Thanks @penguin0616 !

That makes sense. 

That being said, I get the same result as before.

Here's my updated "modmain" code : 

GLOBAL.FOODTYPE.TIER2 = "TIER2"

AddPrefabPostInit("gem",function(inst)
    inst:AddComponent("edible")
    inst.components.edible.foodtype = GLOBAL.FOODTYPE.TIER2
    inst.components.edible.healthvalue = 10
    inst.components.edible.hungervalue = 20
    inst.components.edible.sanityvalue = 5
end)

local function OnEatFirstMeal(inst)
    inst.components.eater:SetDiet({ GLOBAL.FOODTYPE.TIER2 })
	inst.components.inspectable:SetDescription("He looks better, but still hungry! He would love something shiny.")
	SpawnPrefab("flowerhat").Transform:SetPosition(inst.Transform:GetWorldPosition())
end

AddPrefabPostInit("mole", function(inst)
	inst.components.eater:SetOnEatFn(OnEatFirstMeal) -- will now trigger whenever moleworm eats something
end)

I should note that the description does get updated to "He looks better, but still hungry! He would love something shiny."

Thanks a lot for your help! I'm learning a lot thanks to your input

@xovoxx There are no prefabs called "gem" in the game. You need to specify an actual gem.

[xovoxx]

OMG that did it. Thanks a lot!

I thought for sure that prefabs had the same "ID" as the name of their file... Thanks!
