[NEED HELP] Coding: Want to make a character gradually lose sanity under 60% HP

[Monoman]

So I originally used the Walter code to try and edit it but I wasn't able to succeed on that. (I'm generally very new to coding, but really want to make a character mod).

Code:
 

Spoiler

local MakePlayerCharacter = require "prefabs/player_common"

local assets = {
    Asset("SCRIPT", "scripts/prefabs/player_common.lua"),
}

-- Your character's stats
TUNING.ASH_HEALTH = 175
TUNING.ASH_HUNGER = 125
TUNING.ASH_SANITY = 75

-- Custom starting inventory
TUNING.GAMEMODE_STARTING_ITEMS.DEFAULT.ASH = {
    "flint",
    "flint",
    "twigs",
    "twigs",
}

local start_inv = {}
for k, v in pairs(TUNING.GAMEMODE_STARTING_ITEMS) do
    start_inv[string.lower(k)] = v.ASH
end
local prefabs = FlattenTree(start_inv, true)

-- When the character is revived from human
local function onbecamehuman(inst)
    -- Set speed when not a ghost (optional)
    inst.components.locomotor:SetExternalSpeedMultiplier(inst, "ash_speed_mod", 1)
end

local function onbecameghost(inst)
    -- Remove speed modifier when becoming a ghost
   inst.components.locomotor:RemoveExternalSpeedMultiplier(inst, "ash_speed_mod")
end

-- When loading or spawning the character
local function onload(inst)
    inst:ListenForEvent("ms_respawnedfromghost", onbecamehuman)
    inst:ListenForEvent("ms_becameghost", onbecameghost)

    if inst:HasTag("playerghost") then
        onbecameghost(inst)
    else
        onbecamehuman(inst)
    end
end

local function onhealthchange(inst, data, forcesilent)
    if inst.components.health:GetPercentWithPenalty() < 50 then
    inst.components.sanity.dapperness = -1
    elseif inst.components.health:GetPercentWithPenalty() > 50 then
    inst.components.sanity.dapperness = 0
    end
end
-- This initializes for both the server and client. Tags can be added here.
local common_postinit = function(inst) 
    -- Minimap icon
    inst.MiniMapEntity:SetIcon( "ash.tex" )
end

-- This initializes for the server only. Components are added here.
local master_postinit = function(inst)
    -- Set starting inventory
    inst.starting_inventory = start_inv[TheNet:GetServerGameMode()] or start_inv.default
    
    -- choose which sounds this character will play
    inst.soundsname = "willow"
    
    -- Uncomment if "wathgrithr"(Wigfrid) or "webber" voice is used
    --inst.talker_path_override = "dontstarve_DLC001/characters/"
    
    -- Stats    
    inst.components.health:SetMaxHealth(TUNING.ASH_HEALTH)
    inst.components.hunger:SetMax(TUNING.ASH_HUNGER)
    inst.components.sanity:SetMax(TUNING.ASH_SANITY)
    
    -- Damage multiplier (optional)
    inst.components.combat.damagemultiplier = 1
    
    -- Hunger rate (optional)
    inst.components.hunger.hungerrate = 1 * TUNING.WILSON_HUNGER_RATE
    
    inst.OnLoad = onload
    inst.OnNewSpawn = onload
    
    inst:ListenForEvent("healthdelta", onhealthchange)

end

return MakePlayerCharacter("ash", prefabs, assets, common_postinit, master_postinit, prefabs)
 

I'm focused on the line
"local function onhealthchange(inst, data, forcesilent)
    if inst.components.health:GetPercentWithPenalty() < 50 then
    inst.components.sanity.dapperness = -1
    elseif inst.components.health:GetPercentWithPenalty() > 50 then
    inst.components.sanity.dapperness = 0
    end
end"
(Edit of a code line someone else was using) but using this line just caused constant sanity drain whenever health was updated.
Mainly working with this function because its the only one I was able to edit and didn't instantly crash the game. I know Walter has it in his code but I wasn't able to find the exact line, and if I were to use that line of code how would I edit it to fit the character?

Use custom_rate_fn instead.

local function CustomSanityFn(inst, dt)
    local hp = inst.components.health:GetPercentWithPenalty()

    return hp < 0.6 and -1 or 0
end

inst.components.sanity.custom_rate_fn = CustomSanityFn

Thank you so much!! Works as expected.

For the record, in your original code you compare health percent against 50, while the game expect a value between 0 and 1. So use 0.5 for 50%, 0.6 for 60%, etc.
