How to change the items?

[Peovonerb]

hello klei Users I have a favor to ask, I want to create my own mods but I first want to know how to modify files like the crowns here is a example:

 

(first of all! I am not going to steal the mods and I am not taking credit of the same mods all credits are for the ones who made them I am just using them as a example)

 

the obsidian crown from Obsidian Tools PLUS

first of all I want to know how to change the durability of the crown
Here is the Prefab Scripts (please tell me if this is the wrong file):

------------------------------------------------------------------------------------------

I want to first know how to change the durability, time of the barrier and also change the sanity drain of it

[K1NGT1GER609]

Hmm strange I don't see something like:

inst.components.armor:InitCondition(TUNING.ARMOR_OBSIDIANCROWN, TUNING.ARMOR_OBSIDIANCROWN_ABSORPTION) --how many hitpoints it can protect before breaking, percentage the armour protects

near equippable where its usually at. Change the arguments as you wish and read the note I put explaining the arguments respectively. As for sanity drain its under:

 inst.components.armor.ontakedamage = function(inst, damage_amount)
            if owner then
                local sanity = owner.components.sanity
                if sanity then
                    local unsaneness = damage_amount * TUNING.ARMOR_RUINSHAT_DMG_AS_SANITY --math for the first argument
                    sanity:DoDelta(-unsaneness, false) --dodelta subtracts the value in the first argument and second is overtime(bleed?) what ever that means
                end
            end
        end

Change the dodelta argument and/or unsaneness equation. For the duration of the shield length:

owner:DoTaskInTime(--[[Duration]] TUNING.ARMOR_RUINSHAT_DURATION, function()
            fx:RemoveEventCallback("blocked", fx_hitanim, owner)
            fx.kill_fx(fx)
            if inst:IsValid() then
                inst:RemoveTag("forcefield")
                inst.components.armor.ontakedamage = nil
                inst.components.armor:SetAbsorption(TUNING.ARMOR_RUINSHAT_ABSORPTION)
                owner:DoTaskInTime(--[[Cooldown]] TUNING.ARMOR_RUINSHAT_COOLDOWN, function() inst.active = false end) --Cooldown is a timer
            end
        end)
    end

change the tuning.armor_ruinshat_cooldown to the amount of time you want. And I guess that should cover everything asked.
