Anyone know how to "reverse" Willow's sanity gain from fire?

[The_Sp00n]

So I learned that the downside I made for my mod doesn't work. Basically it is the opposite of Willow's passive sanity gain when near fire. So instead of gaining sanity when near fire, the modded character would lose sanity instead. 

 

I tried to just take some code from Willow (listed below) and return delta as negative but it didn't work. I tried making it so the sanity aura was negative and it didn't work. Any ideas bright minds of the forums? (note, the code posted below was all I copied, if I am missing other bits of code or something please tell me what I am missing)


local FIRE_TAGS = { "fire" }
local function sanityfn(inst)--, dt)
    local sanity_cap = TUNING.SANITYAURA_LARGE
    local sanity_per_ent = TUNING.SANITYAURA_TINY
    local delta = inst.components.temperature:IsFreezing() and -sanity_cap or 0
    local x, y, z = inst.Transform:GetWorldPosition()
    local max_rad = 10
    local ents = TheSim:FindEntities(x, y, z, max_rad, FIRE_TAGS)
    for i, v in ipairs(ents) do
        if v.components.burnable ~= nil and v.components.burnable:IsBurning() then
            local stack_size = v.components.stackable ~= nil and v.components.stackable.stacksize or 1
            local rad = v.components.burnable:GetLargestLightRadius() or 1
            local sz = stack_size * sanity_per_ent * math.min(max_rad, rad) / max_rad
            local distsq = inst:GetDistanceSqToInst(v) - 9
            -- shift the value so that a distance of 3 is the minimum
            delta = delta + sz / math.max(1, distsq)
            if delta > sanity_cap then
                delta = sanity_cap
                break
            end
        end
    end
    return delta
end
