Eater component: Make Character Hate a Tag Rather Than Liking Them?


Recommended Posts

I wanted to try to make it so that characters could not eat foods with a certain tag that I could assign to them (let's say "masterfood" as an example, which is all of warly's dishes). What I can do with the eater component is to make it so that characters would only eat foods with the "masterfood" tag to them, thus rejecting all other foods without said tag:

Spoiler



AddPrefabPostInitAny(function(inst)
    if inst:HasTag("player") and inst.components.eater ~= nil and not inst:HasTag("masterchef") then
		inst.components.eater:SetPrefersEatingTag("masterfood")
	end
end)

 

What I could not figure out was how to make it do the opposite; i.e. make it reject foods with the tag "masterfood", but allow all other foods otherwise. 

My attempt to try and make characters hate a tag while accepting all other foods otherwise via some functions based off of SetPrefersEatingTag & PrefersToEat in the eater component, which was doing what I described in the beginning

I think the issue is how I did the HatesToEat function, as I was basing it off what they did for Warly, and I'm not sure how to correct it atm. Characters atm just eat foods normally with this. Any advice would be appreciated on what I'm doing wrong.

--Attempt at making it so that characters can not eat foods with a hated tag, but otherwise act normally.
AddComponentPostInit("eater", function(self)
	
	--Based off of Eater:SetPrefersEatingTag(tag), getting the method for easy use later when telling a character they hate a tag
	function self:SetHatesEatingTag(tag)
		if self.hateseatingtags == nil then
			self.hateseatingtags = { tag }
		else
			table.insert(self.hateseatingtags, tag)
		end
	end
		
	--Based off of Eater:PrefersToEat(inst) to make it so that characters will reject a hated tag
	function self:HatesToEat(inst)
		if self.hateseatingtags ~=nil then
			local preferred = true
			for i,v in ipairs(self.hateseatingtags) do
				if inst:HasTag(v) then
					preferred = false
					break
				end
			end
			if not preferred then
				return true
			end
		end
		return self:TestFood(inst, self.preferseating)
	end
end)

--The process of making the character hate a "masterfood"
AddPrefabPostInitAny(function(inst)
	if inst:HasTag("player") and inst.components.eater ~= nil and not inst:HasTag("masterchef") then
		inst.components.eater:SetHatesEatingTag("masterfood")
	end
end)

 As references, this is what SetPrefersEatingTag looks like:

Spoiler

function Eater:SetPrefersEatingTag(tag)
    if self.preferseatingtags == nil then
        self.preferseatingtags = { tag }
    else
        table.insert(self.preferseatingtags, tag)
    end
end

 

And What PrefersToEat looks like:

Spoiler


function Eater:PrefersToEat(inst)
    if inst.prefab == "winter_food4" and self.inst:HasTag("player") then
        --V2C: fruitcake hack. see how long this code stays untouched - _-
        return false
    elseif self.preferseatingtags ~= nil then
        --V2C: now it has the warly hack for only eating prepared foods ;-D
        local preferred = false
        for i, v in ipairs(self.preferseatingtags) do
            if inst:HasTag(v) then
                preferred = true
                break
            end
        end
        if not preferred then
            return false
        end
    end
    return self:TestFood(inst, self.preferseating)
end

do you need it to be that way because i'm sure that you can create the same effect but by having every food have that tag expect the food you don't want them to eat

or just put in edible component

if food.prefab not (inst your food here) then

food:addtag("your food tagg")

I'm still not sure EXACTLY what you want to accomplish. Can you try to describe the functionality you wish as simply as possible, without referring to any code? Like, "I want specifically my character to not be able to eat a food with a particular tag" or something like that?

--masterpostinit
local _PrefersToEat = inst.components.eater.PrefersToEat
inst.components.eater.PrefersToEat = function(self, food,...)
  return _PrefersToEat(self, food,...) and not food:HasTag("masterfood")
end

Wouldn't just extending the prefers to eat function work? If you just want to refuse those foods?

A) I want characters (except warly) to specifically not be able to eat a food with a particular tag (this part is working now)

B) These tags would be assigned to the foods when made in the portable crockpot (or crockpot X) (Now need to work on).

Yea, that works too and is much simpler than what the final result was. Thanks!
