Help with Custom perks

[Anarchuz]

Hey guys i just started modding, And am creating 4 characters who represent my friends, so we can play as ourself on our server, and just finished my artwork for the first one, compiled it and worked out fine.

now i want to add custom perks to him. I have some experience with  programming, normally i manage fine looking at other peoples scripts, but i cant seem to wrap my head around his one.

 

I want to add these custom perks to my friends characters:

 

-Can eat a gold nugget for a nice, hunger health boost

-Can ONLY eat goldnugget or crockpot recipes, nothing less.

-When finding a goldnugget , gets a nice sanity boost, when loosing one drops same amount

 

i dont expect you guys do make  me al the code, just point me in the right direction, im really eager to learn all of this and make some cool custom characters

 

 

--below first working model of my friends yosisi char, still WIP dont be to harsh with the critics

I was going to point you to Wigfrid to check out SetDiet, but there's a small issue.

Gold nuggets are FOODTYPE.ELEMENTAL, giving you elementals for diet would make you eat a lot more.

Also, crock pot foods don't belong to a specific foodtype.

So you need something more specific.

local crockfoods = require("preparedfoods")-- Perk 2local master_postinit(inst)	inst.components.eater:SetDiet({FOODGROUP.OMNI, FOODTYPE.ELEMENTAL}, {FOODGROUP.OMNI, FOODTYPE.ELEMENTAL})	local self = inst.components.eater	local old = self.Eat	function self:Eat(food, force)		if crockfoods[food.prefab] then			return old(self, food, force)		end		if food.prefab == "goldnugget" then			-- Perk 1			food.components.edible.healthvalue = 10			food.components.edible.hungervalue = 20			food.components.edible.sanityvalue = 5			return old(self, food, force)		end	endend

We import the crockpot foods table list. They don't have a foodtype, so we need to check they are crockpot foods somehow.

We make the character's diet to be almost everything, crock foods and minerals.

However, we override the eating function to make it so crockpot recipes and goldnuggets make the cut and go through.

Also, when we are going to eat a goldnugget, we edit its values right then, so they are unique to the character.

 

What does "finding" and "losing" in your third perk mean?

Somehow my written text dissapeared... But thnx alot for that piece  of code, its gonnaget me started for sure, with finding and loosing i mean, picking a gold nugget up, and with dropping i mean, picking one up or loosing one with crafting or somehting, just the same sanity boost u get for picking flower, but he we also loose sanity of he looses the nugget

[Anarchuz]

btw darkXero, after looking lots of threads i see the most help are yours xD thnx alot of helping so many newbie modders

[DarkXero]

Alright, then it would look like this.

local master_postinit(inst)	inst:ListenForEvent("onpickup", function(inst, data)		if data.item.prefab == "goldnugget" then			inst.components.sanity:DoDelta(5)		end	end)		inst:ListenForEvent("dropitem", function(inst, data)		if data.item.prefab == "goldnugget" then			inst.components.sanity:DoDelta(-5)		end	end)	local self = inst.components.builder	local old = self.RemoveIngredients	function self:RemoveIngredients(ingredients)		for item, ents in pairs(ingredients) do			for k, v in pairs(ents) do				for i = 1, v do					if k.prefab == "goldnugget" then						self.inst.components.sanity:DoDelta(-5)					end				end			end		 end		 old(self, ingredients)	endend

Character gains 5 sanity when picking up gold nugget.

 

Character loses 5 sanity when dropping gold nugget.

 

Character loses 5 sanity for each gold nugget he loses making a recipe.

 

I listen to events that get pushed when performing the PICKUP (has that event right off the bat) and DROP actions (has the event pushed in the DropItem function in Inventory, that executes).

 

I override the builder RemoveIngredients function that the character gets in order to make use of the fact that it gets called to remove ingredients off your inventory when crafting stuff.

Wow thanks dude, you're so much help man ,  hope ill figure to do this myself soon , any tips for good tutorials or other material what could help me learn this? found most videos , but they are pretty basic. 

[Hyaciao]

I'm a beginner just like you. (also just got helped by DarkXero in a pinch). But I figured I might plop my pennies worth, all suggestions might hold some value right?

 

Anyways to the point.

 

How about making a deny all except "x" function? Though this probably not the most elegant solution. (Basing this on the perk where player can't attack specific enemies by listing up specifically which one passes)

In that sense, you can specify what crock pot recipe is acceptable[i'm assuming you don't want them to wet goop] and only gold.

[Anarchuz]

Ok i need to step up my game xD...where can i start to learn this **** xD

[DarkXero]

The only thing I recommend is learning any language, like C. Or maybe python for beginners.

You can always come here to ask.

 

Trying to figure out don't starve by itself is quite a task, since you first learn how the language works, the basics behind lua as a scripting language, and then you learn the paradigms behind the data structures, how classes are implemented, how stategraphs, prefabs and components are linked, etc. I learned by myself, by trial and error, in like 1 to 2 months.

 

By overriding the Eat function, the character gets to put the food on their mouth, but not eat it, he will say "I can't do that."

To make it trigger the spiting animation, you can override the PrefersToEat function.

 

To give the character a very strict diet, we will override the function entirely.

inst.components.eater:SetDiet({FOODGROUP.OMNI, FOODTYPE.ELEMENTAL})local allowed ={	meatballs = true,	goldnugget = true}function inst.components.eater:PrefersToEat(inst)	return allowed[inst.prefab]end

Now he can only eat meatballs and goldnuggets.

Although this is not my thread, I figure I might as well ask since DarkXero recently posted an interesting example:

 

Can I alter the above code components to have it apply to an equipment denial? I am thinking about using the (onequip) (onunequip) command such as below.

inst.components.onequip:SetDiet({WEAPON.OMNI, WEAPON})local allowed ={    spear = true,    pickaxe = true,    axe = true,    torch = true,    }function inst.components.onequip:Weaponlimit(inst)    return allowed[inst.prefab]end

[DarkXero]

No, onequip is not a component. You have all components in scripts/components.

 

Also, onequip tends to be a function that runs after something was equipped, so that check would be pointless.

That is, if the class has the onequip parameter and uses it.

 

Also, there is no such thing as a weaponlimit function.

Ah that makes so much more sense now. Thank you!
