Sanity from Caves

[icantevenname]

I want a character to gain a tiny bit of sanity from caves. I've looked through other characters that do something similar for reference, but they all seem to rely on changing sanity rates for all the other times of the day, and I just want to change the sanity rate in caves only.

you cold check for 

TheWorld:HasTag("cave")

I looked around for some events that occur when travelling between worlds and I found something in components/worldmigrator.lua. This is run whenever you travel: TheWorld:PushEvent("ms_playerdespawnandmigrate", { player = doer, portalid = self.id, worldid = self.linkedWorld })

In components/playerspawner.lua, the event ms_newplayercharacterspawned is pushed to TheWorld after the function SpawnAtLocation is run which I assume is run when the player is actually move from one world to another

In modmain, you could add TheWorld:ListenForEvent("ms_newplayercharacterspawned", function() --[[your function here]] end) For that function, you can make a check using what @krylincy said and then potentially add a sanity aura to the player. If the check returns false you can remove the aura. As for auras, you just add and remove the component as needed. The code might look something like this:
 

local function AddSanityAuraInCaves(player)
    GLOBAL.TheWorld:ListenForEvent("ms_newplayercharacterspawned", function()
		if TheWorld:HasTag("cave") then
			if inst.components.sanityaura == nil then
				player:AddComponent("sanityaura")
			end
			player.components.sanityaura.aura = TUNING.SANITYAURA_SMALL
		elseif inst.components.sanityaura ~= nil then
			player:RemoveComponent("sanityaura")
		end
	end)
end
AddPlayerPostInit(AddSanityAuraInCaves)

I took some of this straight from the update_sanityaura function in sisturn.lua in prefabs. Only here, the subject in question is the player
