How to add a property to an item?

[SilentKid]

Hi! I'm trying to add a sanity-boosting property to a funcap. If I add the line: 

inst.components.equippable.dapperness = TUNING.DAPPERNESS_LARGE

directly to the game file, then everything works. But how can I do this by creating a mod? I found a mod that adds glow to a funcap. When I add my line to the file of this mod, everything works, but I do not know how to rewrite it to remove the funcap glow.

The code that adds the glow:

local function MakeHat(name)
    local fname = "hat_"..name
    local symname = name.."hat"
    local prefabname = symname

    local function onequip(inst, owner)	
		owner.AnimState:OverrideSymbol("swap_hat", fname, "swap_hat")
        owner.AnimState:Show("HAT")
        owner.AnimState:Show("HAIR_HAT")
        owner.AnimState:Hide("HAIR_NOHAT")
        owner.AnimState:Hide("HAIR")

        if owner:HasTag("player") then
            owner.AnimState:Hide("HEAD")
            owner.AnimState:Show("HEAD_HAT")
        end
	
		owner:AddTag("spoiler")

		inst.components.periodicspawner:Start()

		if owner.components.hunger ~= nil then
			owner.components.hunger.burnratemodifiers:SetModifier(inst, TUNING.MUSHROOMHAT_SLOW_HUNGER)
		end
		
		if inst._light == nil or not inst._light:IsValid() then
			if name == "red_mushroom" then
				inst._light = SpawnPrefab("redmushroomlight")
			elseif name == "green_mushroom" then
				inst._light = SpawnPrefab("greenmushroomlight")
			elseif name == "blue_mushroom" then
				inst._light = SpawnPrefab("bluemushroomlight")
			end
		end
		inst._light.entity:SetParent(owner.entity)

		if owner.components.bloomer ~= nil then
			owner.components.bloomer:PushBloom(inst, "shaders/anim.ksh", 1)
		else
			owner.AnimState:SetBloomEffectHandle("shaders/anim.ksh")
		end
	end

	local function turnoff(inst)
		if inst._light ~= nil then
			if inst._light:IsValid() then
				inst._light:Remove()
			end
			inst._light = nil
		end
	end
	
	local function onunequip(inst, owner)
		owner.AnimState:ClearOverrideSymbol("swap_hat")
        owner.AnimState:Hide("HAT")
        owner.AnimState:Hide("HAIR_HAT")
        owner.AnimState:Show("HAIR_NOHAT")
        owner.AnimState:Show("HAIR")

        if owner:HasTag("player") then
            owner.AnimState:Show("HEAD")
            owner.AnimState:Hide("HEAD_HAT")
        end
	
		owner:RemoveTag("spoiler")

		inst.components.periodicspawner:Stop()

		if owner.components.hunger ~= nil then
			owner.components.hunger.burnratemodifiers:RemoveModifier(inst)
		end
		
		if owner.components.bloomer ~= nil then
			owner.components.bloomer:PopBloom(inst)
		else
			owner.AnimState:ClearBloomEffectHandle()
		end
		
		turnoff(inst)
	end

	local function displaynamefn(inst)

How can I force funkap to raise a character's sanity?

The mod you used as a base is way more complicated than what you really need.

In reality, you only need a modinfo.lua file and a modmain.lua file. In modmain.lua, you only need to add this and the mod you want is complete:

local function AddSanity(inst)
  if not GLOBAL.TheWorld.ismastersim then
    return inst
  end
  inst.components.equippable.dapperness = TUNING.DAPPERNESS_LARGE
end

AddPrefabPostInit("red_mushroom",AddSanity)
AddPrefabPostInit("green_mushroom",AddSanity)
AddPrefabPostInit("blue_mushroom",AddSanity)

You will still need to fill the modinfo.lua file with the info it needs, but the modmain.lua file only needs this.

With AddPrefabPostInit you add a function to a prefab that is already existing, in this case your sanity boosting.

Thank you very much for your reply! I did everything exactly as you indicated, but now the game hangs when creating the server.

Have a look at the server log. The error should be written there. If you're not sure what causes it, post the server log here.

After looking at the logs, I only realized that the mod is causing some kind of error. But I can't understand the reason. 

The name of the mod containing your code: "my (Red Mushroom Hat)"

Oh sorry, I had the wrong prefab names. You need to add to each prefab name a hat at the end, so that for example blue_mushroom is changed to blue_mushroomhat.

It works. Thank you! You are my saver
