[Solved (with alternative-coding)] How to make an item add you a tag when equipped?

[Goregonzola]

Hey there!

Long story short: my custom survivor has a constant Health drain, but if he equips his custom item, he would gain Health instead of losing.

My approach was to give a tag to the custom item wielder the time he equips the item, and remove the tag when unequips it.

This is the coding I've came up with:

character.lua, local master_postinit = function(inst) section:

Quote

    if inst:HasTag("mylamp") then
        inst.components.health:StartRegen(3, 2)
    else
        inst.components.health:StartRegen(-2, 3)
    end

item.lua:

Quote

 

local function OnEquip(inst, owner)
    owner.AnimState:OverrideSymbol("swap_object", "swap_wagiclamp", "swap_wagiclamp")
    owner.AnimState:Show("ARM_carry")
    owner.AnimState:Hide("ARM_normal")
    
    if owner and owner:HasTag("lamprenter") then
        inst:AddTag("mylamp")
    end
    
end

local function OnUnequip(inst, owner)
    owner.AnimState:Hide("ARM_carry")
    owner.AnimState:Show("ARM_normal")
    
    if owner and owner:HasTag("lamprenter") then
        inst:RemoveTag("mylamp")
    end
    
end

 

 

I might've put something in the wrong place, since it crashes the game when I equip the item.

Lamprenter is a tag my character always has. I've put the "if" part there, so other survivors don't benefit from the healing, only the custom one.

What should I change?

Thanks in advance guys!

Whats your error log?

I did something similar with the flower amulet. why are you adding the "mylamp" tag to the lamp (inst) itself and not to the owner? maybe that the problem. before you use "inst.components.health:StartRegen(3, 2)" you should check before if the ist has a component and health
"if inst.components ~= nil and inst.components.health ~= nil then" to take care of the client side and owner without health.

the problem is definitely that youre doing "inst:AddTag("mylamp") and not "owner:AddTag("mylamp"). Hope fixing that works

Thanks for the tips!

I've replaced "inst" to "owner", it does not crash now, but it still not restores the character's Health.

I'm kinda clueless...

I'd say, instead of making your custom item add a tag to your character and that way control the regeneration, make it so that the character itself controls it.

For that you could add ListenForEvent("equip") and ListenForEvent("unequip") and add a function that checks whether the item that has been equipped is your custom item.

Example:

local function OnEquipCustom(inst, data)
	if data.item.prefab == "customitem" then
		inst.components.health:StartRegen(3, 2)
	end
end

local function OnUnequipCustom(inst, data)
	if data.item.prefab == "customitem" then
		inst.components.health:StartRegen(-2, 3)
	end
end

inst:ListenForEvent("equip", OnEquipCustom)
inst:ListenForEvent("unequip", OnUnequipCustom)

Yeah, this do seems easier than the Tag-thingy.

I've tried the coding, it works flawlessly.

Much thanks
