Is there a way to make a custom item equippable only when at low sanity

[Random_kin]

I'm trying to make a sword  that does quite a bit of damage but that can only be equipped by someone  whit their sanity  a certain level (let's say 40-20 sanity pt). I tried to make it work but then I realized that I had no idea of what I was doing.

You can make it that when picked up, check if player sanity is within range, if not drop the item, just like how other players can't pick up Lucy the axe

Yeah I've tried that, the game crashed  so I guess it was poor coding on my end. I'll take a look at lucy's code ,thanks.

no luck

I wrote this under  Local Function Mainfunction ()   

inst:DoPeriodicTask(
    2.5,
    function(inst)
     if inst.components.sanity.current>=40 then
         self:DropItem(item)
        self:GiveItem(item)
    end 

   end 

And got this error

If I'm guessing correctly, inst is the hand item entity? Then you'd need:

Spoiler

local owner = inst.components.inventoryitem:GetGrandOwner()

if owner and owner.components.sanity then

-- do some sanity check etc

end

I'm not at my PC right now, do check components/inventoryitem.lua and see if I'm using the correct function to get the item's owner.

This is what I've found inventoryitem.lua .

function InventoryItem:GetGrandOwner()
    if self.owner then
        if self.owner.components.inventoryitem then
            return self.owner.components.inventoryitem:GetGrandOwner()
        else
            return self.owner
        end
    end
end

I've probably  made a mess but it's not working , when I try to equip the weapon it just crashes . Here's the script ,I tried to fix it  without success,

Spoiler

local Assets = { 
    -- Animation files for the item (showing it on the ground and swap symbols for the players).
    Asset("ANIM", "anim/custom_handitem.zip"),
    Asset("ANIM", "anim/custom_handitem_ground.zip"),

    -- Inventory image and atlas file used for the item.
    Asset("ATLAS", "images/inventoryimages/custom_handitem.xml"),
    Asset("IMAGE", "images/inventoryimages/custom_handitem.tex"),
}

local function OnEquip(inst,owner,self)

    inst:DoPeriodicTask(
    2.5,
    function (inst)
      local owner = inst.components.inventoryitem:GetGrandOwner()

      if owner and owner.components.sanity then
        if owner.components.sanity.current>=40 then
             self:DropItem(item)
            self:GiveItem(item)
        end
      end
    end
    )
    -- This will override symbol "swap_body" of the equipping player with your custom build symbol.
    -- Here's what this function is overriding:
    -- owner.AnimState:OverrideSymbol(Player's_symbol, Your_build(*.zip_filename), Symbol_from_your_build(name_of_subfolder_with_art)
    owner.AnimState:OverrideSymbol("swap_object", "custom_handitem", "swap_object")
    
    -- Players have 2 left arms - one of them is hidden when we are not holding an item and vice versa.
    -- Since we want to show an item on equip - hide ARM_normal and show ARM_carry.
    owner.AnimState:Show("ARM_carry")
    owner.AnimState:Hide("ARM_normal")
end

local function OnUnequip(inst, owner) 
    owner.AnimState:Hide("ARM_carry") 
    owner.AnimState:Show("ARM_normal") 
end

local function MainFunction()
    -- Functions which are performed both on Client and Server start here.
    local inst = CreateEntity()
    
    inst.entity:AddTransform()
    inst.entity:AddAnimState()
    inst.entity:AddNetwork()
    inst.entity:AddSoundEmitter()
    
    MakeInventoryPhysics(inst)
    
    -- Add minimap icon. Remember about its XML in modmain.lua!
    local minimap = inst.entity:AddMiniMapEntity()
    minimap:SetIcon("custom_handitem.tex")
    
    --[[ ANIMSTATE ]]--
    -- This is the name visible on the top of hierarchy in Spriter.
    inst.AnimState:SetBank("custom_handitem_ground")
    -- This is the name of your compiled*.zip file.
    inst.AnimState:SetBuild("custom_handitem_ground")
    -- This is the animation name while item is on the ground.
    inst.AnimState:PlayAnimation("anim")

    --[[ TAGS ]]--
    inst:AddTag("custom_handitem")

    MakeInventoryFloatable(inst, "small", 0.05, {1.2, 0.75, 1.2})

    inst.entity:SetPristine()

    if not TheWorld.ismastersim then
        -- If we're not the host - stop performing further functions.
        -- Only server functions below.
        return inst
    end
    

    inst:AddComponent("inspectable")

    inst:AddComponent("inventoryitem")
    inst.components.inventoryitem.imagename = "custom_handitem"
    inst.components.inventoryitem.atlasname = "images/inventoryimages/custom_handitem.xml"
    
    inst:AddComponent("equippable")
    inst.components.equippable:SetOnEquip(OnEquip)
    inst.components.equippable:SetOnUnequip(OnUnequip)

    inst:AddComponent("weapon")
    inst.components.weapon:SetDamage(100)

    MakeHauntableLaunch(inst)

    return inst
end

return  Prefab("common/inventory/custom_handitem", MainFunction, Assets)

Try this:

Spoiler

local function OnEquip(inst, owner, from_ground)    

local function sanity_check()          if owner and owner.components.sanity then             if owner.components.sanity.current>=40 then                owner.components.inventory:Unequip(EQUIPSLOTS.HANDS)             end         end     end     -- Immediately check sanity when equipped     sanity_check()     -- Cancel any existing task     if inst.sanity_check_task then         inst.sanity_check_task:Cancel()         inst.sanity_check_task = nil     end      -- Start a new task     inst.sanity_check_task = inst:DoPeriodicTask(2.5, sanity_check)      -- This will override symbol "swap_body" of the equipping player with your custom build symbol.     -- Here's what this function is overriding:     -- owner.AnimState:OverrideSymbol(Player's_symbol, Your_build(*.zip_filename), Symbol_from_your_build(name_of_subfolder_with_art)     owner.AnimState:OverrideSymbol("swap_object", "custom_handitem", "swap_object")          -- Players have 2 left arms - one of them is hidden when we are not holding an item and vice versa.     -- Since we want to show an item on equip - hide ARM_normal and show ARM_carry.     owner.AnimState:Show("ARM_carry")     owner.AnimState:Hide("ARM_normal") end   local function OnUnequip(inst, owner)     -- Cancel the task     if inst.sanity_check_task then         inst.sanity_check_task:Cancel()         inst.sanity_check_task = nil     end      owner.AnimState:Hide("ARM_carry")      owner.AnimState:Show("ARM_normal")  end

Ehi thanks! So it's working , when sanity is above 40 pt ihe weapon gets unequipped but it doesn't get back into the invetory, it just disappears.
