How to assign tags based on what the diet of the player is?

[lakhnish]

I am trying to assign a tag to players only if they can eat a certain foodtype, as I want to use that tag later on.

The problem is that the tag gets assigned to all players instead of the ones that can eat a certain foodtype in my AddPlayerPostInIt and I'm not sure why.

if inst.components.eater ~= nil then
	for k, v in pairs(inst.components.eater.preferseating) do 
		if inst.components.eater.preferseating[v] == GLOBAL.FOODTYPE.VEGGIE then 
      		     inst:AddTag("vegetarianEater") 
    	      end
  	end
end


if inst:HasTag("vegetarianEater") then
  --my code
end

The reason I am not using foodgroups is because I want to check for specific foodtypes that is part of a foodgroup in the case of modded characters or for someone like Wigfrid. 

In the case above, I would do a c_announce to check if the character was getting the tag when they weren't supposed to (like Wigfrid in this case) and they were getting it.

There's potentially some details I'm missing here, since I'm not sure why all players would be getting the tag based on your loop's conditional.
The correct loop should probably be something like 

if inst.components.eater ~= nil then
	for k, v in pairs(inst.components.eater.preferseating) do 
		if v == GLOBAL.FOODTYPE.VEGGIE or (v.types and table.contains(v.types, GLOBAL.FOODTYPE.VEGGIE)) then
			inst:AddTag("vegetarianEater") 
      			c_announce("Giving 'vegetarianEater' tag to " .. inst:GetDisplayName())
      			break
		end
  	end
end

Since preferseating can have both foodgroups and foodtypes.

The game already adds tags when the diet for an eater is set(This is how the player client is able to know if they can eat a certain food). In the case of a player that can eat veggies only, the "VEGGIE_eater" tag is added.

You can see where the tags are added in the 'scripts/components/eater.lua' file, in the 'oncaneat' function.

What I'm doing is making a diet restriction mod.

I've organized foods into their own categories, assigned a tag to them and then made it so that players can only eat foods with that tag and they would refuse all other foods.

The reason I needed these tags based on if the player can eat a specific foodtype is because not every diet can be eaten by every character, so those characters need to be excluded from the challenge so they can eat what they normally can so they don't starve.

It's really more for modded characters since I could have just used tags that already exist for Wigfrid and Wurt, but this would future proof it as well in case a future character gets another specific diet.

So after the tag assignment, it goes:

AddPlayerPostInIt(function(inst)
    
		--Only those who can eat the veggie foodtype can participate in this challenge as the diet only contains veggies
		if inst.components.eater~=nil and inst:HasTag("vegetarianEater") then
			inst.components.eater:SetPrefersEatingTag("dietNameTag")
		end
    
end)

So with this tag assignment you provided (or with the VEGGIE_eater tag), Wilson and Wurt should only be part of the challenge but for some reason, Wigfrid has become a part of the challenge as well or they all decide that it's time for them to starve and I don't know why.

I'm gonna have to investigate once I have more free time, as this is the only thing that's incomplete to make the mod fully functional 

Edit: I've figured out the problem, it was some other code I had that was interfering.
